| Primary Identifier | MGI:6764667 | Allele Type | Transgenic |
| Attribute String | Recombinase | Gene | Tg(Sprr2f-cre)2Dcas |
| Strain of Origin | C57BL/6 | Is Recombinase | true |
| Is Wild Type | false |
| molecularNote | Using a 189 kb BAC clone (RP23-39I4) containing the entire mouse Sprr2f gene, the cre and neo cassette was inserted into the ATG start codon in exon 2 of the mouse Sprr2f gene via bacterial recombineering method. The neo selection cassette was then excised by transient flippase expression, and the resulting engineered BAC was injected into mouse oocytes for the generation of transgenic founder lines. Five founders had cre insertion, the line 2 was assigned to this transgene in absence of specific line information to distinguish it from Tg(Sprr2f-cre)1Dcas generated by the same creator which showed ectopic cre activity in brain and kidney. This transgene shows specific cre activity only in the uterus and no ectopic expression was observed. |
