Nomenclature: C57BL/6NTac
One of the most used inbred mouse models, the C57BL/6 is used in nearly every research application, and it's commonly used as the genetic background for transgenic mouse models. It is also the preferred model for studying diet-induced obesity and the chronic experimental autoimmune encephalomyelitis model of multiple sclerosis.

B6 males at 7+ weeks of age are packed as cagemates, without recombination of animals from different cages into a single Taconic Transit Cage (TTC). We recommend that customers do NOT recombine 7+ week old B6 males from different Taconic Transit Cages into the same cage at or after unpacking.
Packing Practices
Taconic standard practice is to recombine animals of different home cages and/or ages from a single model and sex during packing, except in specific cases where Taconic's animal welfare policy prohibits recombination due to aggression or other concerns. When an order is fulfilled with animals from more than one week of birth, this standard practice results in animals from a range of birth weeks packed together in a single TTC. When an order is fulfilled with animals from genotyped models, this standard practice results in animals from different home cages packed together in a single TTC.
Customers who wish to keep animals from different weeks of birth separated should place orders with the special instruction "Divide and label by age." Note that this special request can result in increased costs for additional Taconic Transit Cages, dividers and/or freight charges.
Taconic discourages other types of custom packing requests as they can have a negative impact on animal welfare. Learn more.
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 orders sourced from US or Denmark a production minimum 3 gram span is accepted. 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 = 500 per sex at MPF, RF and EF health standards from all global colonies. GF mice will typically weigh slightly less than the weights above.
High and low represents mean +/- 2 standard deviations
Based on sample size, the charts above represent ~90% 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.

Need help choosing the right Taconic Biosciences health standard for your research?
Use the Health Standard Selector to enter your exclusion list. The tool will tell you which health standards meet your requirements.
Speak with a PhD-level Field Application Scientist who can help you select the most appropriate model and maximize your experimental success.
As longtime facilitators of animal-based research, we understand the importance of aligning your project goals and procurement priorities to support advancements in your research.
“Hooke uses the Taconic B6 because we get more consistent disease development for Experimental Autoimmune Encephalomyelitis (EAE) than when using mice from other vendors.”
— Hooke Laboratories
“Taconic Biosciences had provided invaluable support to our course on "Mouse Development, Stem Cells & Cancer". It would be difficult to continue to teach this course at the level we currently do without Taconic's expertise and C57BL/6 mice.”
