| Primary Identifier | MGI:1857621 | Allele Type | Targeted |
| Attribute String | Null/knockout | Gene | Crabp1 |
| Transmission | Germline | Strain of Origin | 129P2/OlaHsd |
| Is Recombinase | false | Is Wild Type | false |
| molecularNote | A genomic fragment containing exons 1 and 2 was replaced with a hygromycin selection cassette inserted in reverse transcriptional orientation relative to the gene. RT-PCR and northern blot analysis on RNA derived from homozygous embryos confirmed that no detectable transcripts were produced from this allele. |
