| Primary Identifier | MGI:2384067 | Allele Type | Targeted |
| Attribute String | Null/knockout | Gene | Cp |
| Transmission | Germline | Strain of Origin | (129X1/SvJ x 129S1/Sv)F1-Kitl<+> |
| Is Recombinase | false | Is Wild Type | false |
| molecularNote | A 3 kb region of the gene including exon 1 and the translation initiation site was replaced with a neomycin resistance cassette via homologous recombination. Southern blot analysis confirmed correct targeting of the allele and Western blot of plasma confirmed the absence of gene expression in homozygous mutant animals. |
