| molecularNote | Exons 1 and 2 were replaced with a PGK-hyg cassette with a 5' loxP site in ES cells containing the Cdkn2atm1.1Brn. Integration occurred on the chromosome that contained the wild-type Cdkn2atm1.1Brn allele. The absence of the p15Ink4b and p16Ink4a protein products was confirmed by western blot analysis on mouse embryonic fibroblasts. |
