| Primary Identifier | MGI:2182628 | Allele Type | Targeted |
| Gene | Efnb2 | Transmission | Germline |
| Strain of Origin | Not Specified | Is Recombinase | false |
| Is Wild Type | false |
| molecularNote | This allele was created to generate Efnb2tm2.1Kln. A modified cDNA of the endogenous locus encoding the full length protein and a hemagglutinin (HA) epitope tag, was inserted immediately downstream of exon 1. The construct also contained a downstream floxed neo gene. |
