Typically heterozygous rats are cryo-recovered in 10-12 weeks to an age of 7 weeks old. Subsequently homozygous rats to an age of 7 weeks old can be produced within 20-22 weeks.
Availability: Cryopreserved as heterozygous embryos
Zygosity: Homozygous as live colony
Homozygous Mrp2 null rats display compromised biliary excretion and hyperbilirubinemia. This results in accumulation of glutathione-conjugated drugs in the liver.
Mrp2 is expressed in the liver and functions in biliary transport. The gene's substrates include anticancer compounds such as vinblastine, enabling it to confer multiple drug resistance to tumor cells. This model is useful for forumational, efficacy, tissue distribution, and DMPK assays
