Origin:
These ZFN mutant rats were produced by injecting zinc finger nuclease targeting rat Npy into iNP/Iusm embryos. A 26-bp deletion, including 6 bp in intron 1 and 20 bp in exon 2 in rat Npy was created in the mutant founders. These mutant founders were backcrossed with iNP/Iusm to produce heterozygous offspring, which were then intercrossed to produce homozygous and heterozygous offspring.
