Strain Details
Type JAX® GEMM® Strain - Mutant Stock Additional information on JAX® GEMM® Strains. Type JAX® GEMM® Strain - Targeted Mutation Species laboratory mouse Donating Investigator Stephen Young, Gladstone Institutes UCSF Generation F?+10p Strain Description
Mice homozygous for the Apobtm2Sgy and Apoetm1Unc targeted mutations do not express the apolipoproteins B48 or E, they do express APOB100. Homozygotes are viable and fertile with no overt abnormalities. Compared to the APOB48 APOE deficient mice and the APOE deficient mice, they have the lowest total cholesterol (247mg/dl), lowest LDL cholesterol, and the least extensive Atherosclerotic lesions. The extent of atherosclerosis correlated significantly with plasma cholesterol levels.Strain Development
The Apobtm2Sgy targeted mutation was generated in a 129 steel derived ES cell line while the Apoetm1Unc mutation was generated in 129P2/OlaHsd-derived E14TG2a ES cells.

|---|---|---|---|
| Allele Name | targeted mutation 2, Stephen G Young | ||
| Common Name(s) | apo-B100; | ||
| Mutation Made By | Stephen Young, Gladstone Institutes UCSF | ||
| Strain of Origin | 129S7/SvEvBrd-Hprt1<+> | ||
| ES Cell Line Name | AB1 | ||
| ES Cell Line Strain | 129S7/SvEvBrd-Hprt1<+> | ||
| Gene Symbol and Name | Apob, apolipoprotein B | ||
| Chromosome | 12 | ||
| Gene Common Name(s) | AI315052; Aa1064; Ac1-060; ApoB-100; ApoB-48; FLDB; expressed sequence AI315052; | ||
| Molecular Note | A "hit and run"-type vector was used to create a CTA to TTA mutation in codon 2153 in sequences corresponding to the apo-B48 editing codon. Western blot analysis on plasma derived from heterozygous and homozygous mice demostrated that the expression of the ApoB100 isoform is unaffected by this mutation, while no ApoB48 isoform is produced from this allele.

| Mutation Made By | Nobuyo Maeda, Univ of North Carolina at Chapel Hill | ||
| Strain of Origin | 129P2/OlaHsd | ||
| ES Cell Line Name | E14TG2a | ||
| ES Cell Line Strain | 129P2/OlaHsd | ||
| Gene Symbol and Name | Apoe, apolipoprotein E | ||
| Chromosome | 7 | ||
| Gene Common Name(s) | AD2; AI255918; LPG; MGC1571; apoprotein; expressed sequence AI255918; | ||
| General Note |
In Apoetm1Unc mutant mice also carrying Csf1op, atherotic lesions of the proximal aorta were abolished or significantly reduced in size relative to Apoe mutants homozygous for the normal allele at Csf1 (J:40136). The results may have been due to reduced macrophages or M-CSF, but were not due to reductions in circulating lipoprotein (J:40136). | ||
| Molecular Note | Insertion of a neomycin resistance cassette deleted part of exon 3 and part of intron 3 of the Apoe gene. Plasma from homozygous mutant mice gave no detectable immunoprecipitate by the Ouchterlony double immunodiffusion test using a rabbit antibody to rat APOE. [MGI Ref ID J:1050] | ||

Supply Details
| Standard Supply | Repository-Cryopreserved. Must Be Recovered. Please refer to pricing and supply notes for further information. |
|---|---|
| Supply Notes |
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
