| Primary Identifier | MGI:7715239 | Allele Type | Endonuclease-mediated |
| Attribute String | Null/knockout | Gene | Igh |
| Transmission | Germline | Strain of Origin | 129S6/SvEvTac |
| Is Recombinase | false | Is Wild Type | false |
| molecularNote | The allele has the mouse immunoglobulin heavy chain complex (Igh) region diversity (D) and joining (J) segments deleted. Specifically, CRISPR/Cas9 genome editing in 129S6/SvEvTac-derived CMTI-1 embryonic stem (ES) cells was used to remove a ~55 kb mouse Igh D-J segment and replace it with a PGK-neomycin resistance cassette. |
