Genotyping through PCR analysis. (a) The PCR product of Pax2-Cre recombinase gene was 319 bp (1). (b) The product of the wild-type allele was 1200 bp and that of the LoxP allele was 1300 bp. A 1200 bp band was detected in the wild-type mice (2). A 1200 bp band and a 1300 bp band were detected in the heterozygous mice (3). Only the 1300 bp band was observed in the homozygous mice (4).
