| Attribute String | Null/knockout | Gene | Adra1d |
| Transmission | Germline | Strain of Origin | 129/Sv |
| Is Recombinase | false | Is Wild Type | false |
| molecularNote | A 0.3 kb fragment of exon 1, which includes the translation initiation codon, was replaced with a PGK-neo cassette via homologous recombination. The knockout allele was confirmed by RT-PCR analysis of various tissues from homozygous mutant animals. No gene expression was detected. |
