| Attribute String | Modified regulatory region, Null/knockout | Gene | Pax6 |
| Transmission | Germline | Strain of Origin | (129X1/SvJ x 129S1/Sv)F1-Kitl<+> |
| Is Recombinase | false | Is Wild Type | false |
| molecularNote | The 341 bp ectoderm enhancer was deleted and replaced with a floxed neo cassette via homologous recombination. Transient expression of cre recombinase in correctly targeted cells removed the floxed neo cassette leaving behind a single loxP site in place of the ectoderm enhancer. PCR genotype analysis confirmed the mutant allele in homozygous animals. |
