| Primary Identifier | MGI:3844713 | Allele Type | Targeted |
| Attribute String | Conditional ready, No functional change | Gene | Ptgs2 |
| Transmission | Germline | Strain of Origin | Not Specified |
| Is Recombinase | false | Is Wild Type | false |
| molecularNote | Exons 6, 7, and 8 that are critical for enzymatic function were flanked by loxP sites. PGE-2 production by activated peritoneal macrophages is unaffected in mice homozygous for this allele, indicating that gene function was not disrupted. |
