Strain Information
Former Names NOD/Lt-Tg(ACTB-Ica1/EGFP)18Mdos/MdosJ (Changed: 23-FEB-07 ) NOD/Lt-Tg(ACTb-Ica1/EGFP)18Mdos/MdosJ (Changed: 17-FEB-05 ) Type Coisogenic; Mutant Strain; Transgenic; Additional information on Genetically Engineered and Mutant Mice. Visit our online Nomenclature tutorial. Species laboratory mouse H2 Haplotype g7 Generation ?+N1p (02-OCT-05)
Generation DefinitionsDonating Investigator H. M. Dosch, University of Toronto Appearance
albino, pink eyed
Related Genotype: A/A Tyrc/TyrcDescription
ACTB-Ica1/EGFP (commonly referred to as Ica69/EGFP) Line 18 transgenic mice are viable, fertile, normal in size, and do not display any gross physical or behavioral abnormalities. Tissue fluorescence is strongest in the heart, intermediate in the exocrine pancreas and kidney and weak in the liver. Tissue fluorescence is observed in isolated transgenic islets. No fluorescence was observed in the brain, thymocytes or spleen cells. NOD transgenic females exhibit reduced diabetes incidence (45%) by 40 weeks of age and more rapid insulitis onset (50%, severe infiltration) at 12 weeks of age compared with NOD controls (80% diabetic by 40 wk and 20% insulitis-positive at 12 weeks). Intra-islet lymphocytes expressing interferon gamma were 50 times more frequent in sections from transgenic Line 18 than in wild-type controls, while IL4 stained cells were barely detectable in either.NOD-Tg(ACTB-Ica1/EGFP)18Mdos/MdosJ can be used as a tool to study the constant over expression of Ica1 in NOD mice and to understand tissue selectively in activating T cells recognizing a widely-expressed antigen.
Development
The fusion transgene ACTB-Ica1/EGFP is under the control of the chicken beta actin (ACTb) promoter and encodes an islet cell autoantigen 1 (Ica1) molecule in which a full-length green florescent protein (EGFP) replaces the Ica1 3' stop codon. This transgenic construct was injected into NOD/Lt oocytes and the resulting founders were backcrossed to NOD/Lt (A. Song and H.M. Dosch et al, unpublished). In 2004, transgenic line 18 arrived at The Jackson Laboratory, was backcrossed to NOD/LtJ one generation and is maintained by hemizygote x +/+ matings.

| Allele Symbol | Tg(ACTB-Ica1/EGFP)18Mdos | ||
|---|---|---|---|
| Allele Name | transgene insertion 18, H Michael Dosch | ||
| Allele Type | Transgenic (Reporter) | ||
| Mutation Made By | H. Dosch, University of Toronto | ||
| Strain of Origin | NOD/ShiLt | ||
| Site of Expression | Strongest in the heart, intermediate in the exocrine pancreas and kidney and weak in the liver. Tissue fluorescence is observed in isolated transgenic islets. No fluorescence was observed in the brain, thymocytes or spleen cells. | ||
| Expressed Gene | GFP, Green Fluorescent Protein, jellyfish | ||
| Green Fluorescent Protein (GFP), derived from the jellyfish Aequorea victoria, is a versatile reporter molecule which has found use in many biological applications. In some constructs the original molecule has been modified in order to enhance its fluorescence intensity (EGFP, enhanced GFP). When utilized in a transgenic construct, tissue expressing sufficient amounts of GFP will fluoresce when exposed to a 488 nm light source. | |||

| General Note | Line 18 transgenic mice are viable, fertile, normal in size, and do not display any gross physical or behavioral abnormalities. NOD transgenic females exhibit reduced diabetes incidence (45%) by 40 weeks of age and more rapid insulitis onset (50%, severe infiltration) at 12 weeks of age compared with NOD controls (80% diabetic by 40 wk and 20% insulitis-positive at 12 weeks). Intra-islet lymphocytes expressing interferon gamma were 50 times more frequent in sections from transgenic Line 18 than in wild-type controls, while IL4 stained cells were barely detectable in either. | ||
| Molecular Note | A chicken beta actin promoter drives the expression of the fusion gene Ica1/EGFP, which encodes an islet cell autoantigen 1 (Ica1) molecule in which a full-length enhanced green florescent protein (EGFP) replaces the Ica1 natural 3'-stop codon. Tissue fluorescence is strongest in the heart, intermediate in the exocrine pancreas and kidney and weak in the liver. Tissue fluorescence is observed in isolated transgenic islets. No fluorescence was observed in the brain, thymocytes or spleen cells. | ||

The average number of mice provided from recovery of our cryopreserved strains is 10. The total number of animals provided, their gender and genotype will vary. We will fulfill your order by providing at least two pair of mice, at least one animal of each pair carrying the mutation of interest. Please inquire if larger numbers of animals with specific genotype and genders are needed. Animals typically ship between 11 and 14 weeks from the date of your order. If a second cryorecovery is needed in order to provide the minimum number of animals, animals will ship within 25 weeks. IMPORTANT NOTE: The genotypes of animals provided may not reflect the mating scheme utilized by The Jackson Laboratory prior to cryopreservation, or that discussed in the strain description. Please inquire about possible genotypes which will be recovered for this specific strain. The Jackson Laboratory cannot guarantee the reproductive success of mice shipped to your facility. If the mice are lost after the first three days (post-arrival) or do not produce progeny at your facility, a new order and fee will be necessary.Cryorecovery to establish a Dedicated Supply for greater quantities of mice.
Mice recovered can be used to establish a dedicated colony to contractually supply you mice according to your requirements. Price by quotation.

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 Information
