C57BL/6J Mouse (JAX™)

Nomenclature: C57BL/6J

Type: Inbred mice

Origin: The C57BL/6 mouse was developed by C.C. Little in 1921, after crossing the female N.57 with the male N.52 from a commercial breeding centre in the United States (Miss Abby Lathrop). It was introduced into The Jackson Laboratory in 1948, at F22, then to Charles River Laboratories France in 1981 and UK in 2004. Breeding is in accordance with The Jackson Laboratory genetic management system. 

C57BL/6J is the most widely used inbred strain and the first to have its genome sequenced. Although this strain is refractory to many tumors, it is a permissive background for maximal expression of most mutations. C57BL/6J mice are resistant to audiogenic seizures, have a relatively low bone density, and develop age related hearing loss (this strain is homozygous for Cdh23^ahl). They are also susceptible to diet-induced obesity, type 2 diabetes, and atherosclerosis. Macrophages from this strain are resistant to the effects of anthrax lethal toxin.

Coat color: Black

Strain code: 632

Ideal for: General multipurpose model, diet-induced obesity, transgenic/knockout model development, safety and efficacy testing, immunology
