Origin: National Institutes of Health (USA) - 1996 (F184) 

Strain name: BALB/cAnNRj 

Type : Inbred mouse 

Colour and related genotype: Albino mouse 

Breeding: Good breeder with better performances than BALB/cJRj and BALB/cByJRj mice 

This strain was selected by MacDOWELL from an albino outbred stock and then sent to Dr SNELL (The Jackson Laboratory) in 1935 (generation F26). The “c” was added by Dr SNELL to indicate that the genotype at the colour locus was c/c (albinism). In 1935, Dr SNELL sent breeders to Drs HESTON an ANDERVONT at the NIH. Dr ANDERVONT’s substrain was incorporated into NIH main colonies in 1951. BALB/cAnNRj mice achieve better ascites production than other strains derived from Dr ANDERVONT’s. BALB/cAnNRj mice can show ulcerative blepharitis and periorbital abscesses. They can also present with hydrocephalus and malocclusion. Due to its good breeding performance, this strain is used in the production of embryos for transgenesis (QUICKBLASTO®). The QUICKBLASTO®, a JANVIER LABS’s product, is a kit containing straws of frozen embryos at the morula stage (C57BL/6NRj or BALB/cAnNRj). With these embryos, after thawing and culture, you will have blastocysts ready to receive your embryonic stem cells.
