| Primary Identifier | MGI:2152451 | Allele Type | Targeted |
| Attribute String | Null/knockout | Gene | Grb2 |
| Transmission | Germline | Strain of Origin | (129X1/SvJ x 129S1/Sv)F1-Kitl<+> |
| Is Recombinase | false | Is Wild Type | false |
| molecularNote | A genomic fragment containing exons 2 and 3 was replaced with a vector containing a neomycin selection cassette by homologous recombination. Immunoprecipitation and western blotting experiments on cell lysates derived from homozygous mice confirmed that no detectable protein was made from this allele. |
