Origin: Created by JANVIER LABS in 2015, principle pair F0/N11 

Strain name: B6/Rj-Tyrc/c 

Type : Inbred mouse 

Colour and related genotype: Albino mouse - Tyrc/c 

Breeding: Good breeder 

This strain was developed by crossing a C57BL/6NRj with a BALB/cAnNRj and the B6cF1 was backcrossed over 10 generations with a C57BL/6NRj genetic background. The result: an inbred mouse with a C57BL/6NRj genetic background carrying the albino mutation. The B6(C)/Rj-Tyrc/c, therefore, has absolutely no pigments (skin, eyes). This strain also possesses characteristics similar to a C57BL/6NRj, but does not carry the Nnt gene mutation, unlike the C57BL/6JRj. The B6(C)/Rj-Tyrc/c is mainly used in transgenics for the creation of blastocysts intended for the reception of genetically modified ES cells by way of microinjection on a C57BL/6 genetic background. This strain can also be used by immunology, such as the C57BL/6. It is, in this case, used in the production of embryo kits, from zygotes to blastocyst stage.
