A transposon transgene containing mouse Pgk2 driving expression of sleeping beauty 10 (SB10) and a mouse tyrosinase minigene driven by a Tyr enhancer flanked by Sleeping Beauty inverted repeats (termed
pT-Tybs-3'E) were co-injected with a Pgk2 driven SB10. In line 1498, transposon and transposase co-integration results in a 66.8 kb deletion containing the coding exons of the targeted gene and none of the coding regions of the genes flanking the integration site. RT-PCR confirmed the absence of transcript expression at P0 skin cDNA.
