| Primary Identifier | MGI:2660761 | Allele Type | Targeted |
| Attribute String | Null/knockout | Gene | Gfi1 |
| Transmission | Germline | Strain of Origin | (129X1/SvJ x 129S1/Sv)F1-Kitl<+> |
| Is Recombinase | false | Is Wild Type | false |
| molecularNote | The gene was disrupted by replacement of exons 2-4, and part of exon 5, with a neomycin resistance cassette via homologous recombination. Absence of gene expression in homozygous mutant animals was confirmed by Western blot analysis of thymus proteins. |
