Mouse mating protocol
NettetMost protocols use two hormones to mimic the effects of endogenous follicle stimulating hormone (FSH) and luteinizing hormone (LH) through the injection of pregnant mare serum gonadotropin (PMSG) followed by human chorionic gonadotropin (hCG), with an interval of 42–48 h between the two hormones. NettetF1 mice carrying the mutated allele or chimeric mice known to transmit the mutation at high frequency should be used for further mating or to create conditional KO animals. If using other mating schemes or strains in which color cannot be used as a indicator of ES cell germline transmission, all pups must be genotyped.
