The CAPAN-1 cell line, which has 6174delT mutation in the single BRCA2 allele, expresses a truncated BRCA2 protein of 230 kDa that contains the Anti-BRCA2 epitope and retains RAD51 binding but has lost p53 binding. Full length BRCA2 protein will co-migrate on SDS-PAGE with the catalytic subunit of DNA PK which can be detected using Anti-DNA PK, Cat. No. PC127. Antibody should be titrated for optimal results in individual systems.
