| molecularNote | A loxP flanked region extending from region extending from 4 kb upstream of exon 1 through 1 kb of intron 1, and including the FRT-flanked neo cassette, was excised from Sema3ftm1Ddg via cre mediated recombination in the germline. Transcript was undetected by Northern blot analysis of homozygous mutant mice. |
