This immunodeficient nude mouse originated from NIH and was originally thought to be a BALB/c congenic. It was later determined that it was not inbred and is therefore maintained as an outbred. It is not associated with any stock or strain. The animal lacks a thymus, is unable to produce T cells, and is therefore immunodeficient. To Charles River from NCI in 2010. Model Properties: Coat Color: Hairless, albino background…

The Endosafe ® nexgen-MCS™ is capable of concurrently testing up to five samples within 15 minutes for fast, quantitative, and accurate endotoxin results.
Congenic Strain Production Congenic strains are widely used in biomedical research because they reduce genetic variability and provide insight into the contribution of genetic background to phenotype. Congenic strains are identical at all genetic loci except for one; that differing locus is usually the transgene or knock-out region of interest. Utilizing traditional, random backcrossing methods, it takes 10 generations (upw…
The 11BHSD2 mouse was produced by injection of a construct, containing 11β-HSD2 cDNA isolated from mouse kidney and cloned into plasmid Clone 26 to recruit the 5.4 kb mouse α–myosin heavy chain (α-MHC) promoter, into pronuclei of C57BL/6 embryos. Transgenic mice were maintained by sibling mating and used as hemizygotes. Model Properties: Coat Color: Black Ideal For: Cardiac hypertrophy, heart failure Strain Code: 510 HE,…
NSE-p25 mice were created by pronuclear injection of an NSE-p25 transgene, produced internally at Pfizer, with transplantation of embryos to pseudopregnant CD-1 females. At weaning genomic DNA was isolated from tail tissue and founder transgenics were identified by PCR that specifically amplified DNA sequences from the human p25 cDNA. Founder mice were bred to FVB/N mates and transgenic offspring were used to maintain the tra…
Developed by C.C. Little in 1921, from a mating of Miss Abby Lathrop’s stock that also gave rise to strains C57BR and C57L. Strains 6 and 10 separated about 1937. To Hall in 1948 from The Jackson Laboratory. To NIH in 1951 from The Jackson Laboratory at F32. To Charles River in 1974 from NIH. Model Properties: Coat Color: Black MHC Haplotype: H2b Ideal For: general multipurpose model, diet-induced obesity, transgenic…
Silvers and Billingham began brother x sister matings with selection for histocompatibility in 1958 from a brown mutation in a stock of wild rats maintained by King and Aptekman in a pen-bred colony of rats trapped from the wild in 1930 by King at the Wistar Institute. To Charles River from Radiobiology Institute, Netherlands in 1976. Model Properties: Coat Color: Non-agouti brown MHC Haplotype: RT1n Ideal For: Geneti…
The New Zealand White rabbit was obtained in 1991 by Charles River Canada (CRC) from Kitayama Labs K.K. of Nagano Prefecture, Japan. Model Properties: Coat Color: White (albino) Ideal For: General multipurpose model Strain Code: 052
Developed from a line of Crl:CD(SD) rats. Two lines were developed from this outbred colony, the OP-CD (Obese Prone) and OR-CD (Obese Resistant). This model becomes obese when fed high-fat diets. Obesity develops despite having a fully functioning leptin receptor. The control for this model is the Crl:OR(CD). Model Properties: Coat Color: White (albino) Ideal For: obesity, metabolic syndrome Strain Code: 463
PCSK9 mice were created utilizing a full-length human PSK9 cDNA with a C-terminal V5 tag expressed under the transcriptional control of a composite human albumin promoter containing a 235 bp SV40 enhancer and a 213 bp albumin promoter element. A chimeric intron was inserted between the promoter and PCSK 9 cDNA to enhance expression. The expression cassette was flanked by a 1.2 kb insulator sequence from the chicken beta-globu…
Okamoto, Kyoto School of Medicine, 1963, from outbred Wistar Kyoto male with marked elevation of blood pressure mated to female with slightly elevated blood pressure. Brother x sister mating with continued selection for spontaneous hypertension was then started. To NIH in 1966 from Okamoto at F13. To Charles River from NIH in 1973 at F32.Model Properties: Coat Color: White (albino) MHC Haplotype: RT1k Ideal For: genet…

A mutation occurred in a colony of outbred Zucker rats in the laboratory of Dr. Walter Shaw at Eli Lilly Research Laboratories in Indianapolis, IN in 1974–75. Part of this colony containing the mutation was moved to Indiana University Medical School (IUMS), to the laboratory of Dr. Julia Clark in 1977. Several groups of animals with diabetic lineage were identified and rederived in 1981. Inbreeding of selected pairs from this…
