| Attribute String | Null/knockout | Gene | Mmp12 |
| Transmission | Germline | Strain of Origin | 129X1/SvJ |
| Is Recombinase | false | Is Wild Type | false |
| molecularNote | The gene was disrupted by replacement of the majority of exon 2 with a PGK-neo cassette via homologous recombination. Gene transcription and protein production was absent in homozygous mutant animals as demonstrated by Northern and Western blot analysis of peritoneal macrophages and peritoneal fluid. |
