| Primary Identifier | MGI:2660562 | Allele Type | Targeted |
| Attribute String | Null/knockout | Gene | Tlr9 |
| Transmission | Germline | Strain of Origin | 129P2/OlaHsd |
| Is Recombinase | false | Is Wild Type | false |
| molecularNote | A 1.0 kb fragment of the gene encoding a part of a leucine-rich repeat domain was replaced with a neomycin resistance cassette. Northern blot analysis demonstrated that a mutated transcript was expressed from this allele, but this transcript is not expected to produce a functional protein. |
