Strain Details
Type JAX® GEMM® Strain - Mutant Stock Additional information on JAX® GEMM® Strains. Type JAX® GEMM® Strain - Transgenic Species laboratory mouse Donating Investigator Andrew Leiter, Univ. of Massachusetts Medical School Important Note
This strain is homozygous for Gnat2cpfl3, cone photoreceptor function loss 3, which affects bright light (photopic) vision.Strain Description
Mice hemizygous for the transgenic insert are viable, fertile, normal in size, and do not display any gross physical or behavioral abnormalities. Expression of the transgene is directed by a neurogenin 3 promoter. Tissues where Cre recombinase expression is detected include the small intestine (base of intestinal crypts) and fetal pancreatic epithelial cells. Cre activity has been shown in islets of the adult pancreas, small intestine enteroendocrine cells, endocrine portions of the stomach, all pancreatic endocrine cells, and in some non-endocrine intestinal cells. When bred with a mouse containing a loxP site-flanked sequence of interest, Cre-mediated recombination results in deletion of the flanked gene in the tissues that normally express neurogenin 3.Strain Development
A bacterial artificial chromosome (BAC) encoding the mouse neurogenin 3 sequence was modified by the insertion of a Cre recombinase gene, preceded by nuclear localization sequence, into exon 1 of the neurogenin 3 gene at the initiator methionine. The BAC was injected into FVB/N embryos which were next implanted into pseudopregnant CD1 females. Founder line C1 was obtained and backcrossed to CD1 mice for 7 generations after which mice were intercrossed.

| Allele Name | transgene insertion C1, Andrew B Leiter | ||
| Common Name(s) | Tg(Neurog3-cre)#Able; ngn3-Cre; | ||
| Mutation Made By | Andrew Leiter, Univ. of Massachusetts Medical School | ||
| Site of Expression | small intestine (base of intestinal crypts) and fetal pancreatic epithelial cells | ||
| Expressed Gene | cre, cre recombinase, bacteriophage P1 | ||
| Cre recombinase is an enzyme derived from the bacteriophage P1 that specifically recognizes loxP sites. Cre has been shown to effectively mediate the excision of DNA located between loxP sites. After the excision event, the DNA ends recombine leaving a single loxP site in place of the intervening sequence. | |||
| Promoter | Neurog3, neurogenin 3, rat | ||
| General Note | This is one of two independent lines demonstrating identical expression patterns. | ||
| Molecular Note | The Cre recombinase coding sequence, flanked by a nuclear localization signal and an SV40 polyadenylation site, was inserted just after the translation start site of the neurogenin 3 gene present in mouse BAC RP23-121F10, which also includes approximately 81 kb of 5' and 102 kb of 3' flanking DNA. Immunohistochemical analysis shows the same expression pattern for cre as for neurogenin 3 in adult and embryonic mice bearing this transgene. Cre recombinase activity is seen in cell types of pancreas, stomach, small intestine and colon that express or are descended from cells that express neurogenin 3 during development.

Cryopreserved Embryos This strain is also available as cryopreserved embryos from our Repository. Orders for cryopreserved embryos are supplied subject to a signed agreement that must be returned to the Customer Service Department after order placement. Experienced technicians at The Jackson Laboratory have recovered frozen embryos of this strain successfully. We will provide you enough embryos to perform two embryo transfers. The Jackson Laboratory does not guarantee successful recovery at your facility. For complete information on purchasing embryos from our repository, please visit our Cryopreserved Embryos web page. Cryorecovery - Standard. The recovery process begins when a signed agreement form is returned to the Customer Service Department after order placement. Although results vary by strain, at least two males and two females (two pairs) will be provided, typically within 15 weeks of our receipt of the signed agreement form. If the first recovery attempt is unsuccessful or only one pair is recovered, a second recovery will be done, extending the delivery time to approximately 25 weeks. At least one member of each pair will be of known genotype and will carry the mutation if it is a mutant strain. Please note that pairs may not reflect the mating scheme utilized by The Jackson Laboratory prior to cryopreservation of the strain. Mating schemes are sometimes modified for successful cryopreservation. Price represents a repository maintenance fee, which includes the cost of recovery of the strain from the cryopreservation resource and the periodic replacement of the frozen embryos used for recovery. Cryorecovery to establish a Dedicated Supply for greater quantities of mice. |

The Jackson Laboratory's Genotype Promise
The Jackson Laboratory has rigorous genetic quality control and mutant gene genotyping programs to ensure the genetic background of JAX® Mice strains as well as the genotypes of strains with identified molecular mutations. JAX® Mice strains are only made available to researchers after meeting our standards. However, the phenotype of each strain may not be fully characterized and/or captured in the strain data sheets. Therefore, we cannot guarantee a strain's phenotype will meet all expectations. To ensure that JAX® Mice will meet the needs of individual research projects or when requesting a strain that is new to your research, we suggest ordering and performing tests on a small number of mice to determine suitability for your particular project.Ordering and Purchasing Information
