Genetic Background:

FVB Background


The Mrp2 mouse was developed in the laboratory of Alfred Schinkel of the Netherlands Cancer Institute. The model was created through targeting of the Abcc2 gene in 129/Ola-derived E14 ES cells and injecting the targeted cells into C57BL/6 blastocysts. Resultant chimeras were backcrossed to FVB/N for seven generations (N7). Taconic received stock in 2006, and the line was embryo transfer derived. The colony is maintained by mating homozygotes.


Wild type for Nnt mutation; carries Pde6brd1 mutation
