| molecularNote | An isoform specific mutation was generated by replacing the coding region of exon 1B with a floxed neomycin selection cassette. RT-PCR analysis verified that sequence upstream of the insertion, encoding the A isoform, was transcribed. Transcript encoding the B isoform was undected in homozygous mutant mice by RT-PCR analysis. |
