| Primary Identifier | MGI:3849964 | Allele Type | Targeted |
| Attribute String | Conditional ready, No functional change | Gene | Tgfb1 |
| Transmission | Germline | Strain of Origin | 129S6/SvEvTac |
| Is Recombinase | false | Is Wild Type | false |
| molecularNote | A floxed neomycin cassette was placed upstream of exon 6 with an additional loxP site placed downstream of exon 6. The neomycin cassette was subsequently removed by transient expression of cre recombinase leaving exon 6 floxed. Germline transmission of the allele was confirmed by genomic PCR. |
