Genetic Background:

C57BL/6JBomTac Background


The Black 6 Bom inbred model was developed by Little et al. Hall received stock. Jackson Laboratory received stock from Hall in 1948. Zentralinstitut für Versuchsteirzucht, Hannover Germany (Han) received stock in 1971. M&B A/S (now Taconic Europe) received stock at F141 in 1988. The mice were derived by embryo transfer in January 2000.

The Taconic US foundation colony was at F156 + 35 in 2005.

  • The C57BL/6JBomTac substrain carries a mutation in the Y chromosome. More information is available in the following two papers: MacBride MM et al. Mild reproductive impact of a Y chromosome deletion on a C57BL/6J substrain. Mamm Genome 2017; 28(5-6):155-165 and Fischer M et al. Large deletion on the Y-chromosome long arm (Yq) of C57BL/6JBomTac inbred mice. Mamm Genome 2017; 28(1-2):31-37.

For some applications, weight may be critical. For orders where weight is critical, please place orders by weight, not by age. Taconic can accept orders by weight for this model for mice sourced from European colonies only. A minimum 3 gram span is required. All weights are weights at time of packing. Mice and rats can lose weight in transit. Orders for specific weight spans will be assessed a nominal fee. More detail on weight order policies is available.

n= 80 per sex at MPF health standard from EU production colonies. Data collected 2014-15.
High and Low represent mean +/- 1 standard deviation.
Based on sample size the charts above represents ~65% of the population.
All growth curves represent animals housed in our barriers, at our standard density and fed NIH31-M diet. Variations at customer facilities will alter expected growth curves. Growth charts are provided only as a guide, if a specific weight criteria is needed please order animals by weight.

  • They have a high preference for ethanol and morphine, and are susceptible to streptozotocin-induced diabetes. This strain is relatively resistant to mycobacterium leprae murium infection.

Taconic mice do not carry the Nnt Mutation
