| 008233 | B6.129-Nrgntm1Kph/J | Repository- Live |
| Homozygous neurogranin-deficient (Ng-/-) mice are viable and fertile (although the donating investigator reports that homozygous females do not nurse their pups as well as wildtype or heterozygous mothers). Homozygotes have no mRNA or protein from the targeted gene observed in brain tissues. Expression of lacZ is observed in a manner consistent with the endogenous gene. Ng-/- mice exhibit impaired spatial learning, altered hippocampal short- and long-term plasticity (including long-term potentiation induction), and decreased activated CaMKII. Heterozygotes show similar, yet milder, effects. These neurogranin- (Ng or RC3)-mutant mice may be useful for neurological studies involving memory and learning, neuronal signaling pathways (including calmodulin, alpha-CaMKII, protein kinase A, protein kinase C, MAPK, and CREB), attention deficit-hyperactivity disorder (ADHD), and schizophrenia. | ||
| 008451 | B6.129P(Cg)-Ptprca Cx3cr1tm1Litt/LittJ | Repository- Live |
| Mice that are homozygous for the CX3CR1-GFP targeted mutation are viable, fertile, normal in size and do not display any gross physical or behavioral abnormalities. RT-PCR analysis of lymphoid tissue from homozygotes detects mutant gene product (mRNA) and no wild type gene product (mRNA). Flow cytometric analysis of peripheral blood cells identified a subset of green fluorescent cells not observed in wild type mice. Enhanced Green Fluorescent Protein (EGFP), but not the endogenous gene, is expressed in monocytes, dendritic cells, NK cells, and brain microglia, mimicking endogenous gene expression. The same subset of peripheral blood cells isolated from heterozygote mice express detectable levels of EGFP. Immunohistochemical analysis of spleen and peripheral nerve tissue from homozygotes does not detect EGFP. These mice also express the CD45.1 (Ly5.1 or Ptprca) allele, which is atypical for the C57BL/6 congenic background, and this marker may be used to track donor cell popul

| 005491 | B6.Cg-Mapttm1(EGFP)Klt Tg(MAPT)8cPdav/J | Repository- Live |
| Mice that are homozygous for the targeted allele and hemizygous for the transgene are viable and fertile. Although no endogenous mouse MAPT is detected, all six isoforms (including both 3R and 4R forms) of human MAPT are expressed. Hyperphosphorylated MAPT is detected in cell bodies and dendrites by three months of age. Paired helical filaments of aggregated insoluble MAPT can be isolated from brain tissue as early as two months of age. These mutant mice may be useful in studies examining the relationship between human MAPT and Alzheimer's disease pathogenesis In an attempt to offer alleles on well-characterized or multiple genetic backgrounds, alleles are frequently moved to a genetic background different from that on which an allele was first characterized. It should be noted that the phenotype could vary from that originally described. We will modify the strain description if necessary as published results become available. | ||
| 005317 | B6.Cg-Tg(BAT-lacZ)3Picc/J | Repository- Live |
| Mice homozygous for the transgenic insert are viable, fertile, normal in size and do not display any gross physical or behavioral abnormalities. These "BAT-GAL" transgenic mice are a reporter strain that express beta-galactosidase in the presence of activated beta-catenin. The transgene expresses the lacZ gene under the control of a regulatory sequence consisting of seven consensus LEF/TCF-binding motifs upstream of the Xenopus siamois gene minimal promoter. Transgenic mice display beta-galactosidase activity beginning at embryonic day 6.0 in the posterior side of the proximal epiblast. Beta-galactosidase expression is detectable in the posterior primitive streak and node at gastrulation, and progresses to the paraxial mesoderm and notochord. Beta-galactosidase activity in developing and adult nervous tissue mimics the pattern of Wnt signaling. When bred to other mutant strains, this reporter strain may be useful for identifying mutations that affect the Wnt-signalling pa

| 005029 | B6.Cg-Tg(Hlxb9-GFP)1Tmj/J | Repository- Live |
| These transgenic mice express Green Fluorescent Protein (GFP) under the direction of the mouse Hlxb9 promoter. Mice homozygous for the transgenic insert are viable, fertile, do not display any gross behavioral abnormalities, but are smaller in size than wildtype littermates. Homozygous pups born to homozygous females have a high mortality rate. Transgenic mice display distinct expression of GFP in dendrites, axons and soma of spinal motor neurons, allowing identification, isolation and purification of spinal motor neurons by FACS. GFP expression mimics endogenous HLXB9 expression pattern. Fluorescence is detected in axons, dendrites and processes of spinal motor neurons at embryonic day 9.5 to postnatal day 10 aged mice. This mutant mouse strain represents a model that may be useful for purification and in vivo tracking of spinal motor neurons. | ||
| 007902 | B6.Cg-Tg(RP23-268L19-EGFP)2Mik/J | Repository- Live |
| Mice hemizygous for the ChAT(BAC)-eGFP (ChATBAC-eGFP) transgene are viable and fertile, with the endogenous choline acetyltransferase (ChAT) transcriptional regulatory elements (cholinergic gene locus) directing enhanced green fluorescent protein (EGFP) protein expression during development as well as in the adult mouse. As such, EGFP is expressed in central and peripheral cholinergic neurons, including cell bodies and processes of the somatic motor, somatic sensory, and parasympathetic nervous system in gastrointestinal, respiratory, urogenital, cardiovascular, and other peripheral organ systems and neuromuscular junctions. These ChAT(BAC)-eGFP transgenic mice allow fluorescent visualization of cholinergic elements of the central and peripheral nervous system and may be useful for studying cholinergic neurotransmission and neuromuscular coupling. | ||
| 007894 | B6.Cg-Tg(Rgs4-EGFP)4Lvt/J | Repository- Live |
| Hemizygous RGS4 BAC transgenic mice are viable and fertile. As the RGS4 BAC transgene has an IRES2-eGFP construct inserted into the 3' UTR of the regulator of G-protein signaling 4 (Rgs4) locus, transgenic RGS4 transcripts and EGFP protein expression is observed in a pattern consistent with endogenous Rgs4. While the transgene is designed to co-express EGFP and RGS4, over-expression of RGS4 is not reported to result in unfaithful reporting of endogenous RGS4 expression. Under the control of the RGS4 promoter/enhancer elements, transgene expression reports dynamic developmental, regional, and cellular specific expression in developing and mature cerebral cortex neurons across all cortical domains, as well as developing and mature subcortical regions (telencephalon, diencephalon, and brainstem). While immunostaining against the transgenic product ("RGS4-GFP") allows detailed cellular resolution of neuronal cell bodies and processes, the subcellular localization of EGFP cann

| 007901 | B6.Cg-Tg(Thy1-Brainbow1.0)HLich/J | Repository- Live |
| These Thy1-Brainbow 1.0 (line H) transgenic mice are viable and fertile. The mice possess multiple fluorescent protein sequences uniquely flanked with pairs of incompatible Lox sites alternated to create mutually exclusive recombination events; allowing stochastic expression of multiple fluorescent proteins from a single transgene. Prior to Cre-mediated recombination, the fluorescent protein immediately adjacent to the promoter, tdimer2(12) (RFP), is expressed in peripheral and central neurons. When bred to Cre recombinase expressing mice, the resulting offspring can have one of three expression outcomes for each transgene in each cell of the cre expressing tissue(s): tdimer2(12) (RFP) (no recombination), mYFP, or mCerulean (CFP). A palmitoylation sequence tethers the mYFP and mCerulean (CFP) to the membrane, allowing clear labeling of axonal processes, while cytoplasmic tdimer2(12) (RFP) better labeled neuronal cell bodies and dendrites.

The mice possess multiple fluorescent protein sequences uniquely flanked with pairs of incompatible Lox sites alternated to create mutually exclusive recombination events; allowing stochastic expression of multiple fluorescent proteins from a single transgene. Although the fluorescent protein immediately adjacent to the promoter, Kusabira-Orange (kOFP), was designed to be expressed prior to Cre-mediated recombination, basal kOFP expression is not observed in mouse tissues. When bred to Cre recombinase expressing mice, however, the resulting offspring can have one of three expression outcomes for each transgene in each cell of the cre expressing tissue(s): mCerulean (CFP), mYFP, or mCherry (RFP). The resulting fluorescent protein expression is observed in astrocytes of all areas of the brain and spinal cord, as well as dentate gyrus granule cells.

| 007921 | B6.Cg-Tg(Thy1-Brainbow2.1)RLich/J | Repository- Live |
| These Thy1-Brainbow 2.1 (line R) transgenic mice are viable and fertile. The mice possess two invertible DNA segments (four fluorescent protein sequences in total) uniquely positioned in tandem and flanked with LoxP sites to generate a larger number of recombination outcomes; allowing stochastic expression of multiple fluorescent proteins from a single transgene. Although the fluorescent protein immediately adjacent to the promoter, hrGFPII (with nuclear localization signal), was designed to be expressed prior to Cre-mediated recombination, basal hrGFPII expression may not be observed in mouse tissues. When bred to Cre recombinase expressing mice, however, the resulting offspring can have one of three different inversions for each transgene in each cell of the cre expressing tissue(s). In addition, two excision events may reduce the construct to one of two single invertible DNA segments which can continue to invert as long as cre is present. These different recomb

| 006401 | B6;129P-Trpa1tm1Kykw/J | Repository- Live |
| Homozygous mice are viable and fertile. The donating investigator reports a dramatic loss of fecundity after 5-6 months of age. The targeting vector contains an endoplasmic reticulum (ER) retention signal (KDEL), which is reported to sequester the potential truncated mRNA product in the ER. The vector also contains an IRES-PLAP reporter gene, allowing extracellular antibody staining/chromogenic development tracking of cells normally expressing the endogenous gene. Homozygous mice display behavioral deficits in response to mustard oil, cold, and punctate mechanical stimuli. These mice have a normal startle reflex to loud noise, a normal sense of balance, a normal auditory brainstem response, and normal transduction currents in vestibular hair cells. These mutants may be useful in neurobiological studies involving dorsal root ganglion neurons and cells of the inner ear, as well as for auditory, temperature, or chemical irritant trials. | ||
| 006465 | B6;CBA-Tg(CAG-lacZ-WGA)330Bbm/J | Repository- Live |
| These ZW transgenic mice constitutively express lacZ under the control of the CMV enhancer/chicken actin promoter. Expression is widespread, but mosaic, throughout the central and peripheral nervous systems. Purkinje cells display intense beta-galactosidase activity. Approximately 50% of the total neuron population express the transgene, as detected by beta-galactosidase activity. Newborn mice exhibit widespread beta-galactosidase activity. When crossed with a Cre recombinase-expressing strain, lacZ expression is replaced with wheat germ agglutinin (plant lectin) expression in tissues expressing cre. The double reporter system makes it possible to distinguish a lack of reporter (lacZ) expression from a lack of Cre recombinase expression while providing a means to assess Cre excision activity at the individual cell level. This transgenic mouse strain may be useful in tracing transneuronal or trans-synaptic connections and circuits in brain regions or in the s

| 007910 | B6;CBA-Tg(Thy1-Brainbow1.0)LLich/J | Repository- Live |
| These Thy1-Brainbow 1.0 (line L) transgenic mice are viable and fertile. The mice possess multiple fluorescent protein sequences uniquely flanked with pairs of incompatible Lox sites alternated to create mutually exclusive recombination events; allowing stochastic expression of multiple fluorescent proteins from a single transgene. Prior to Cre-mediated recombination, the fluorescent protein immediately adjacent to the promoter, dTomato (RFP), is expressed in peripheral and central neurons. When bred to Cre recombinase expressing mice, the resulting offspring can have one of three expression outcomes for each transgene in each cell of the cre expressing tissue(s): dTomato (RFP) (no recombination), mCerulean (CFP), or mYFP. Integration of tandem transgene copies yields combinatorial fluorescent protein expression in each cell, and thus many possible cell colors, providing a way to distinguish adjacent neurons and visualize other cellular interactions.

| 004690 | B6;FVB-Tg(Pcp2-EGFP)2Yuza/J | Repository- Live |
| These transgenic mice express Enhanced Green Fluorescent Protein (EGFP) under the direction of the mouse Purkinje cell protein 2 promoter. Mice hemizygous for the transgene are viable, fertile, normal in size and do not display any gross physical or behavioral abnormalities. Transgenic mice display distinct expression of EGFP in dendrites, axons and soma of Purkinje cells, allowing identification, isolation and purification of Purkinje cells by FACS. EGFP expression mimics endogenous Purkinje cell protein 2 expression pattern. Fluorescence is detectable at embryonic day 17 in Purkinje cells and also occurs in retinal bipolar cells. Low levels of fluorescence are seen in olfactory periglomerular cells, interpeduncular nucleus and superior colliculus neurons. This mutant mouse strain represents a model that may be useful for purification and in vivo tracking of Purkinje cells. | ||
| 006043 | B6;SJL-Tg(Oxt/EGFP)AI03Wsy/J | Repository- Live |
| Hemizygous mice are viable and fertile with no gross or behavioral abnormalities. This transgene expresses an enhanced green fluorescent protein (EGFP) fused to the end of the neurophysin at the C-terminus of the oxytocin pre-prohormone. The transgene is selectively expressed in oxytocin-magnocellular neurons of the paraventricular and supraoptic nuclei of the hypothalamus. The fusion protein is faithfully trafficked to secretory granules and transported to neurosecretory terminals in the neurohypophysis, where the EGFP fluorescence undergoes depolarization-induced calcium-dependent secretion. Immunohistochemical detection of EGFP in individual oxytocin-magnocellular neurons is suggested as intrinsic fluorescence is low. However, the endogenous fluorescence in the neural lobes is sufficiently intense to image secretory events in individual oxytocin nerve terminals (neurosecretosomes) isolated from the posterior pituitary. These mice may be useful in studies of hormone biology, pharmaco

| 007677 | CB6-Tg(Gad1-EGFP)G42Zjh/J | Repository- Live |
| Mice hemizygous for this GAD67-GFP transgene are viable and fertile. GAD67-GFP (line G42) mice selectively express enhanced green fluorescent protein (EGFP) in the calcium-binding protein parvalbumin (Pv)-expressing subclass of basket interneurons (soma, dendrites, and axons) and also in putative presynaptic boutons. While transgene expression (EGFP expression) is published as early as postnatal day 0 (P0) with high expression levels throughout postnatal development, the donating investigator additionally reports transgene expression as early as embryonic day 14 (E14). EGFP expression is not reported in other interneuron classes positive for somatostatin (SOM), cholecystokinin (CCK), calretinin (CR), and VIP. These GAD67-GFP (line G42) mice may be useful for fluorescent labeling of the Pv-expressing subset of GABAergic neurons, allowing reliable and efficient characterization of perisomatic innervation in vivo. Of note, this GAD67-GFP strain is one of many fluorescent GABAerg

| 003718 | FVB-Tg(GadGFP)45704Swn/J | Repository- Live |
| Mice homozygous for the TgN(GadGFP)45704Swn transgene express Enhanced Green Fluorescent Protein (EGFP) under the control of the mouse Gad1 (GAD67) gene promoter. Homozygous mice exhibit no apparent physical or behavioral defects. Transgene expression occurs in a specific subpopulation of hippocampal and cortical GABAergic interneurons that express somatostatin. This subset of interneurons has been shown to be prone to injury during epilepsy, ischemia, and Alzheimer's disease. These transgenic mice are useful for the morphological identification and study of these interneurons in both living and fixed brain tissue. Of note, this strain is one of many fluorescent GABAergic neuron strains, each with unique labeling characteristics (see Stock No. 006334 and Stock No. 006340). | ||
| 007225 | FVB.129(B6)-Usp18tm1Dzh/J | Repository- Live |
| Homozygous Usp18 (or Ubp43) mutant mice on the FVB/N genetic background are viable and fertile, exhibiting none of the severe neurologic disorders that lead to embryonic lethality or early death reported for Ubp43-deficient mice on a C57BL/6 or mixed B6;129 genetic background. In contrast to wildtype mice, thymi from homozygous mice injected with LPS exhibit no protein from the targeted gene. Expression of the lacZ cassette is observed in both heterozygous and homozygous brain tissues. Homozygous mice are hypersensitive to type I interferon (IFN) and undergo apoptosis upon IFN stimulation. Ubp43-deficiency results in enhanced and prolonged STAT1 phosphorylation, DNA binding, and increased induction of hundreds of interferon stimulated genes (ISGs). Homozygous mice exhibit greater resistance to the cytopathic effects caused by a number of viruses (including lymphocytic choriomeningitis virus (LCMV), vesicular stomatitis virus (VSV), and Sindbis virus (SNV)).

| Mice that are homozygous for the targeted mutant Smn1 allele and carry the SMN2 transgene exhibit symptoms and neuropathology similar to patients afflicted with type I proximal spinal muscular atrophy (SMA). In the initial characterization by the donating investigator, mice were either stillborn or survived 4-6 days. Mice that died at or shortly after birth were slightly smaller (1.33 g. vs. 1.51 g.) than normal littermates. Mice that survive for several days are indistinguishable from normal littermates in the first 48 hours, after which they exhibit decreased suckling and movement, labored breathing and tremoring limbs. Mice succumbing at this later time point are noticeably smaller than normal littermates (1.47 g vs. 4.59). A bell-shaped trunk is also noticeable in affected mice, presumably from intercostal muscle weakness, a characteristic of type I SMA. Histological analysis indicates that affected mice that survive to day 5 exhibit a loss of motor neurons from spina

| Mice that are homozygous for the targeted mutant Smn allele and homozygous for the SMN2transgene and hemizygous for the SMN1*A2G transgenes exhibit symptoms and neuropathology similar to patients afflicted with type III (mild) proximal spinal muscular atrophy (SMA). These same animals with only one copy of the SMN2transgene are 20%-40% smaller than unaffected mice. At 3 weeks of age they become less active and show signs of muscle weakness. The mice have a shortened lifespan (less than a year) near the end of which they exhibit reduced movement, diminished grooming, shallow breathing and considerable weight loss. Immunohistochemical analysis of spinal cord tissue from 1 month-old animals indicates the presence of cytoplasmic SMN protein and intranuclear aggregates (gems) of the SMN protein. The number of gems is however, fewer than the number found in age matched control tissues. Histological analysis of muscle tissue (gastrocnemius, quadriceps, and intercostals mu

| This triple mutant mouse harbors two transgenic alleles and a single targeted mutant. The Tg(SMN2*delta7)4299Ahmb allele consists of a SMA cDNA lacking exon 7 whereas the Tg(SMN2)89Ahmb allele consists of the entire human SMN2 gene. Mice that are homozygous for the targeted mutant Smn allele and homozygous for the two transgenic alleles exhibit symptoms and neuropathology similar to patients afflicted with proximal spinal muscular atrophy (SMA). At birth, triple mutants are noticeably smaller than normal littermates. By day 5, signs of muscle weakness are apparent and become progressively more pronounced over the following week as the mice display an abnormal gait, shakiness in the hind limbs and a tendency to fall over. Mean survival is approximately 13 days. Immunocytochemical analysis indicates that dystrophin expression is normal, however fibers isolated from the gastrocnemius muscle of a 14 day old triple mutant clearly show evidence of atrophy.

| 004779 | STOCK Mapttm1(EGFP)Klt/J | Repository- Live |
| Mice that are homozygous for the transgenic insert are viable, fertile, normal in size and do not display any gross physical or behavioral abnormalities. A knock-in of the EGFP coding sequence into the first exon disrupts expression of the Mapt gene and produces a cytoplasmic EGFP fused to the first 31 amino acids. No gene product (isoform proteins) is detected in whole brain lysates by Western blot analysis. EGFP signal is detected beginning at 9.0 days post coitum in the trigeminal ganglion and by 10.75 days post coitum fluorescent signal is detected throughout the developing central nervous system. EGFP expression persists to adult and closely patterns the expression of neuron specific beta-tubulin III, as detected by the TuJ1 antibody. The expression of cytoplasmic EGFP in the central nervous system of this mutant allows for non-invasive visualization of elongating nerve axons. | ||

Under control of the Math1 (Atoh1) enhancer, tamoxifen-inducible cre activity is observed in neural progenitors of the cerebellar rhombic lip, dorsal hindbrain and spinal cord, as well as in inner-ear primordia (with a limited amount of ectopic expression in the primordium of the hippocampus but not the cortex). The Cre-ERT2 fusion protein consists of Cre recombinase fused to a triple mutant form of the human estrogen receptor; which does not bind its natural ligand (17b-estradiol) at physiological concentrations but will bind the synthetic estrogen receptor ligands 4-hydroxytamoxifen and, with lesser sensitivity, ICI 182780. Restricted to the cytoplasm, Cre-ERT2 can only gain access to the nuclear compartment after exposure to tamoxifen.

| Hemizygous mice are viable, fertile, normal in size, and do not display any gross physical or behavioral abnormalities. Cre activity is observed in parasagittal domains of the cerebellum beginning at embryonic day 17 (E17). At E19, low level expression is observed in the most rostral lobe of cerebellum and expression broadens until all Purkinje cells express the transgene in adult mice. When bred with any mouse containing a loxP-flanked sequence of interest, Cre-mediated recombination will result in deletion of the flanked genome. These transgenic mice may be useful in studies utilizing “Cre-lox” technology, specifically regarding the nervous system, development and patterning of cerebellum, and cerebellar hypotrophy converse of Lhermitte-Duclos. | ||

| These transgenic mice conditionally express Enhanced Yellow Fluorescent Protein (EYFP) under the direction of the mouse thymus cell antigen 1, theta, promoter. Expression of the EYFP gene is blocked by a loxP-flanked STOP fragment placed between the promoter and EYFP gene. Cre-mediated excision of the STOP cassette results in expression of EYFP in motor neurons. Mice hemizygous for the transgenic insert are viable, fertile, normal in size and do not display any gross physical or behavioral abnormalities. For example, when crossed to a strain with widespread expression of Cre recombinase (see Stock No. 003376), this mutant mouse strain may be useful in studies of synaptic function. | ||

| These mutant mice express synapto-pHluorin (spH) from the endogenous locus encoding the olfactory marker protein (OMP) as a result of a targeted knockin mutation that replaces the OMP coding region with that of spH. The OMP locus directs expression of spH at high levels and exclusively in mature sensory neurons of the main olfactory epithelium (OSNs) and the vomeronasal epithelium. SpH is a pH-sensitive variant of the green fluorescent protein (ecliptic pHluorin) fused to the mouse synaptic vesicle-associated protein (VAMP2). The protein is localized preferentially in synaptic vesicles, but is also present on the plasma membrane of OSN axons and nerve terminals. The fluorescent domain of spH is exposed to the acidic lumen of synaptic vesicles where it is ~ 20 fold less fluorescent than at neutral pH. Upon synaptic release, the lumen of the synaptic vesicles becomes continuous with the extracellular space resulting in an increase in pH that causes a rapid increase in fluorescence. In mu

| Mice homozygous for the transgenic insert are viable, fertile, normal in size and do not display any gross physical or behavioral abnormalities. Expression of the transgenic lacZ gene is directed by upstream activating sequence (UAS) elements. This strain serves as a reporter for mice employing GAL4/UAS bigenic system for controlled gene expression in the developing CNS. In this system, a transgenic strain expressing the yeast transcriptional activator GAL4 (see Stock No. 003829) is bred to a second transgenic, target strain bearing an UAS-regulated gene. In the double transgenic offspring, an UAS-regulated gene would be selectively expressed in tissues expressing GAL4. | ||
| 005621 | B6;D2-Tg(S100B-EGFP)1Wjt/J | Repository-Cryopreserved |
| Mice homozygous for the transgenic insert are viable, fertile, normal in size and do not display any gross physical or behavioral abnormalities. These transgenic mice express Enhanced Green Fluorescent Protein (EGFP) under the direction of the human S100 calcium-binding protein, beta (neural) promoter. Fluorescence is detected in Schwann cells of the sternomastoid, soleus, extensor digitorum longus, triangularis sterni and diaphragm muscles, some astrocytes, Bergmann glia and a few muscle macrophages. EGFP expression is detected at birth. This mutant mouse strain may be useful in studies of vital imaging of neuronal and glial cells, and neuromuscular junctions. | ||
| 005620 | B6;D2-Tg(S100B-EYFP)1Wjt/J | Repository-Cryopreserved |
| Mice homozygous for the transgenic insert are viable, fertile, normal in size and do not display any gross physical or behavioral abnormalities. These transgenic mice express Enhanced Yellow Fluorescent Protein (EYFP) under the direction of the human S100 calcium-binding protein, beta (neural) promoter. Fluorescence is detected in Schwann cells, motor axons, microglia, a subset of Bergmann glia and some muscle macrophages. Strong fluorescent signal is detected in the Schwann cells of sternomastoid, extensor digitorum longus, triangularis sterni and diaphragm muscles and in the motor axons of the triangularis sterni. EYFP expression is detected at birth in glial cells and at postnatal day 7 in motor axons. This mutant mouse strain may be useful in studies of vital imaging of neuronal and glial cells. | ||
| 004127 | FVB-Tg(Nes-rtTA)306Rvs/J | Repository-Cryopreserved |
| Mice that are hemizygous for this transgene are viable, fertile, normal in size, and do not display any gross physical or behavioral abnormalities. These transgenic mice express the reverse tetracycline-controlled transactivator (rtTA) protein under the control of the rat nestin intron II enhancer/promoter. According to the donating investigator, expression occurs in the neuroepithelium of the developing nervous system (embryonic days 10-17), in some neuron subsets of the adult mouse (e.g. cerebellum, hippocampal dentate gyrus, subventricular zone, spinal cord) and in adult testes. The rtTA gene is cotranscribed with the lacZ reporter gene Bgeo, which allows verification of the site of rtTA expression. When Tg(Nes-rtTA) hemizygous mice are mated to a second transgenic strain carrying a gene of interest under the regulatory control of a tetracycline-responsive promoter element (TRE; tetO), expression of the target gene may be regulated by the tetracycline analog, doxycycli

| 006334 | STOCK Tg(Gad1-EGFP)94Agmo/J | Repository-Cryopreserved |
| Mice hemizygous for the transgenic insert are viable, fertile, normal in size and do not display any gross physical or behavioral abnormalities. These transgenic mice express Enhanced Green Fluorescent Protein (EGFP) under the direction of the mouse Gad1 (glutamic acid decarboxylase 1 or GAD67) promoter. In the forebrain, EGFP expression is restricted to the somatosensory barrel neocortex, mostly in laminar layers 4 and 5B, to a lesser extent in layers 2/3, 5A and upper 6. EGFP expression is also found in subsets of cerebellar interneurons and in the brainstem. In founder line 94 transgenic mice fluorescence is observed in neocortical neurons with axonal arborizations in layer 4 that have a stuttering firing pattern. Fluorescence levels are low in animals younger than 2 weeks of age. The fluorescently labeled subset of somatostatin-containing (SOM+) interneurons in founder line 94 transgenic mice is distinct from the population of neurons labeled in founder line 98 (Stock No.

New Strains Under DevelopmentThe Jackson Laboratory serves as a worldwide distributor and national repository for common and rare strains of inbred mice and mice carrying spontaneous mutations or induced mutations (i.e., transgenic, targeted/"knockout", or chemically induced mutations). At any one time, we have over 100 strains at various stages of development and colony expansion. Strains "Under Development" fall into two categories depending on the anticipated demand from the scientific community.
- Receive periodic updates on the status of the colony UNDER DEVELOPMENT
- Obtain advance notification of strain availability and opportunity to order prior to the strain being published as available
- Provide input affecting speed and quantity of availability
It is VERY IMPORTANT that you register interest in strains Under Development. The anticipated demand for a strain enables us to determine effectively the distribution plan for each strain Under Development. Registering interest also provides benefits to you (including advance notification of pending availability). Whether a strain is made available from a live colony OR from our cryopreservation repository, you may want to consider the option of Dedicated Supply. To learn more about Dedicated Supply, go to Services.
- Strains that will be made available from a live distribution colony at The Jackson Laboratory.
These strains are designated as: "Under Development for Distribution Colony"- Strains that will be made available through the Cryopreservation Repository.
