Mouse anti Human p53 antibody, clone DO-1 recognizes the human p53 tumor suppressor protein, also known as cellular tumor antigen p53 or NY-CO-13. The antibody binds to both wild type and mutant forms of the p53 protein found in various malignancies (Kern et al. 1992).

The p53 protein is important in multicellular organisms, where it regulates cell cycle progression to allow DNA repair or apoptosis in the case of irreparably damaged cells (Haupt et al. 2003) and thus functions as a tumor suppressor,  involved in preventing cancer. Mutations in the p53 gene are found in about half the cases of human cancer (Joerger and Fersht 2007).

Mouse anti Human p53 antibody recognizes an epitope at the N-terminal end of p53 between amino acids 20-25, common to isoforms 1-3 of p53 and detects a band of ~53 kDa on HEK293 cell lysates by western blotting under reducing conditions.
