| Transmission | Germline | Strain of Origin | (129X1/SvJ x 129S1/Sv)F1-Kitl<+> |
| Is Recombinase | false | Is Wild Type | false |
| molecularNote | Exons 2 through 9, containing the entire coding region, were deleted by the insertion of a neomycin selection cassette. Northern blot analysis showed that transcript encoded by the endogenous allele was absent in homozygous mutant embryos. Assays of plasma obtained from homozygous mutant mice showed a lack of amidolytic activity. |
