| Primary Identifier | MGI:1857853 | Allele Type | Targeted |
| Attribute String | Null/knockout | Gene | Nrp1 |
| Transmission | Germline | Strain of Origin | (C57BL/6NCrlj x CBA/JNCrlj)F1 |
| Is Recombinase | false | Is Wild Type | false |
| molecularNote | A neomycin cassette replaces sequences encoding the a1 domain of the protein. The mutant allele was expected to encode only the signal peptide and the most N-terminal 7 amino acid residues of the protein. Immunohistochemical analysis of homozygous mutant embryos demonstrated the lack of intact protein. |
