| Primary Identifier | MGI:2651421 | Allele Type | Targeted |
| Gene | Oprm1 | Transmission | Germline |
| Strain of Origin | Not Specified | Is Recombinase | false |
| Is Wild Type | false |
| description | ES cell line = SP1. |
| molecularNote | The endogenous allele was disrupted by the insertion of a targeting vector containing a missense mutation in exon 2 and an intron floxed neo cassette. Encoded protein was undetected by radioactive ligand receptor-binding assay. Oprmtm2.1Loh was generated by in vivo excision of the floxed neo cassette from this allele. |
