Wild-type transcripts were not detected in the mutant. +, wild-type allele; m, mutant allele.f. Real-time RT-PCR analysis of total RNA from E10.5 embryos. The coding regions amplified by different primer pairs are indicated on the left. Expression levels in wild-type are set to 100 percent. Expression levels in the mutants on average are less than 3 percent of wild-type for all coding regions 3’ to the site of gene targeting. +, wild-type allele; m, mutant allele.The following primer pairs were used:Unc5b: ACAGGCACTCCCTCCGGTGG/ATCGTCTATGTGAATGGAGG
