A promoterless IRES-LacZ-neomycin resistance cassette containing a 5' En-2 intron and splice acceptor site replaced exons 17-21. Northern analysis of homozygous mutant E12.5 embryos using an exon 15 probe detected a 12.5kb fusion transcript, and did not detect the wild-type transcript. Western analysis using an anti-beta-galactosidase antibody detected the predicted 146kDa beta-galactosidase-neomycin fusion protein in homozygous mutant embryos. (J:72238)
