| Attribute String | Recombinase | Gene | Bhlhe22 |
| Transmission | Germline | Strain of Origin | 129/Sv |
| Is Recombinase | true | Is Wild Type | false |
| molecularNote | The coding region of the Bhlhe22 gene was replaced by the coding sequence of cre recombinase and a loxP flanked neo selection cassette via homologous recombination in ES cells. The neo was removed in the ES cells by cre-mediated excision. |
