What is the difference between C57BL 6 and C57BL 6J?
What is the difference between C57BL 6 and C57BL 6J?
C57BL/6J is the parental substrain; “J” is the laboratory code for The Jackson Laboratory. Therefore, there is no source of “C57BL/6” mice; there is always a longer designation for each substrain indicating the institute or laboratory that maintains the different colonies.
Are C57BL 6 mice genetically modified?
C57BL/6 Mouse Details C57BL/6 mice are the most used inbred strain in research. Our C57BL/6 mouse colonies are genetically identical within each strain, making them free of genetic differences that could impact research results.
What does C57BL 6 stand for?
C57 black 6
C57BL/6, often referred to as “C57 black 6”, “C57” or “black 6”, is a common inbred strain of laboratory mouse. It is the most widely used “genetic background” for genetically modified mice for use as models of human disease.
Are C57BL 6 mice aggressive?
Although some consider C57BL/6 mice to be aggressive, in general they are not when compared to other mouse strains. However, they may appear to be more aggressive because they are the most commonly used mouse strain in research and thus there are many of them to observe.
Why are C57BL 6 mice used?
C57BL/6 mice is an inbred mouse strain originally developed for the study of antitumor activity and immunology, and is increasingly being used as an basic background strain. It is known that cell-mediated immunity and NK cell activity are of relatively high importance in determining immunological characteristics.
How much does a C57BL 6 cost?
Specialized Inventory

Why do we use C57BL 6 mice?
How long do c57bl6 mice live?
The median lifespan of C57 range from 27 to 29 months and the maximum around 36 months.
Can male mice be housed together?
While male mice do not live together in the wild and will fight upon contact, suggesting they should not be housed together in the lab, early pairing and the marked decreased in isolation stress make it worth it. They are social animals, but compete with other males.
Are C57BL 6 mice inbred?
C57BL/6 mice is an inbred mouse strain originally developed for the study of antitumor activity and immunology, and is increasingly being used as an basic background strain.
Why are C57BL 6J mice used?
Where did the C57BL / 6 substrain come from?
The substrain “6” was the most popular of the surviving substrains. Little’s supervisor William E. Castle had obtained the predecessor strain of C57BL/6, “mouse number 57”, from Abbie Lathrop who was breeding inbred strains for mammary tumor research in collaboration with Leo Loeb at the time.
Is there such a thing as a C57BL / 6N mouse?
The longer individual substrains are separated from each other, the greater the number of genetic differences between them. These genetic differences can lead to phenotypic differences. In 1951, C57BL/6J mice were sent to the National Institutes of Health (NIH) where a colony was established and was called C57BL/6N.
Which is the most common strain of C57BL?
By far, however, the C57BL/6 strains are the most commonly published in the world with over 37,000 entries in PubMed (Table 3). For this reason, this paper will focus on published differences only in the C57BL/6 family.
What is the laboratory code for C57BL / 6J?
As part of a strain’s nomenclature, Laboratory codes are added at the end as the substrain designation. C57BL/6J is the parental substrain; “J” is the laboratory code for The Jackson Laboratory.
