It is the most widely used "genetic background" for genetically modified mice for use as models of human disease. They are the most widely used and best-selling mouse strain due to the availability of congenic strains, easy breeding, and robustness. [1] The median lifespan of C57BL/6 mice is 27–29 months and the maximum lifespan is about 36 ...
The sale of mouse animal models began in 1933 with early sales to the United States Public Health Service and The Jackson Laboratory now provides a high proportion of the mice used in biomedical research [16] In particular, the C57BL/6J strain, which is widely used and cited is maintained at The Jackson Laboratory.
Unlike most laboratory mouse strains, the C57BL/6 drinks alcoholic beverages voluntarily. It is more susceptible than average to morphine addiction, atherosclerosis, and age-related hearing loss. [11] When compared directly to BALB/c mice, C57BL/6 mice also express both a robust response to social rewards [43] [44] and empathy. [45]
Mouse Genome Informatics (MGI) is a free, online database and bioinformatics resource hosted by The Jackson Laboratory, with funding by the National Human Genome Research Institute (NHGRI), the National Cancer Institute (NCI), and the Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD).

C57BL/6 was created by Clarence Little, the first director and founder of JAX. However, he created the strain in 1921 (see here on the JAX site), whereas the Jackson Labs didn't come into being until 1929. In addition, JAX may be the largest supplier of C57BL/6J, but it probably is not the largest supplier of some other substrains, such as ...
All laboratories using vertebrate lab animals in the United States are required by law to have a licensed veterinarian on staff and to adhere to the NIH Guide for the Use and Care of Laboratory Animals, which further stipulates that all protocols, including the sources for obtaining the animals, must be reviewed by an independent committee.

The adults can be easily distinguished from common laboratory mice from their size and body colours. They are slightly smaller, and they have characteristic two-coloured body, agouti with white bellies. [2] The two colours are not marked by a distinct margin but fused as the colour fades. The tail is also bi-coloured, white with a black tip.
Mus musculus B16F10 skin melanoma cells in laboratory. B16 melanoma is a murine tumor cell line used for research as a model for human skin cancers. B16 cells are useful models for the study of metastasis and solid tumor formation, and were one of the first effective murine tools for metastasis research. These cells readily metastasize to lymph ...
