| Primary Identifier | MGI:3715912 | Allele Type | Targeted |
| Attribute String | Null/knockout | Gene | Dntt |
| Transmission | Germline | Strain of Origin | 129S/SvEv-Gpi1<c> |
| Is Recombinase | false | Is Wild Type | false |
| description | Analyses were performed only in chimeric mice. |
| molecularNote | A targeting vector was used to eliminate the Dntt promoter and exon 1 by homologous recombination. Terminal deoxynucleotidyl transferase enzymatic activity or transcripts from the mutant allele are not detected in Dntt-null thymocytes by RNA blotting. |
