NCI: Derived from a cross between a C57BL/6 female and a C3H male, this hybrid strain is commonly used in the production of transgenic mice. B6C3F1 hybrid females are used as egg donors in the creation of transgenic mice as their breeding performance is robust and the pronuclei of their fertilized eggs are prominent, allowing for ease of microinjection.,NCI: Derived from a cross between a C57BL/6 female and a C3H male, this hybrid strain is commonly used in the production of transgenic mice.
