Fig. 1. F1 mouse genotyping by gel electrophoresis. The lanes with the bands of PCR products with the size of about 300 bp (fragment of STOP cassette) and about 400 bp (fragment of terminator) correspond to transgenic mice. The lanes with no bands correspond to the wild type mice. The first and the last lanes contain the size markers
