Picture of PCR genotyping results and table demonstrating numbers and gender of animals for each experiment. (a) Results from genomic PCR analysis of 9 representative animals. On the left side 100 bp DNA ladders are visible. In the upper panel all analyzed mice show a wt band at 308 bp. In the lower panel an additional knockout band at 1600 bp is visible in 4 animals (Tor1a+/-). (b) Table shows the number and gender of mice used for the experiments. (TIF 14399 kb)
