Scientific Data Images for Human Phospho-p53 (S37) Antibody
Detection of Human Phospho-p53 (S37) by Western Blot.
Western blot shows p53 immunoprecipitated from lysates of MCF-7 human breast cancer cell line using Human/Mouse/Rat p53 Agarose-conjugated Antigen Affinity-purified Polyclonal Antibody (Catalog # GAF1355). MCF-7 cell line was untreated (-) or treated (+) with 1 µM camptothecin (CPT) for 5 hours. PVDF membrane was probed with 0.4 µg/mL Rabbit Anti-Human Phospho-p53 (S37) Antigen Affinity-purified Polyclonal Antibody (Catalog # AF3306) followed by HRP-conjugated Anti-Rabbit IgG Secondary Antibody (Catalog # HAF008). A specific band for Phospho-p53 (S37) was detected at approximately 53 kDa (as indicated). The phospho-specificity of this antibody was supported by decreased labeling following treatment with 600 U lambda-phosphatase (lambda-PPase) for 1 hour. For additional reference the membrane was stripped and reprobed with 1:5000 dilution of Human/Mouse/Rat p53 HRP-conjugated Antigen Affinity-purified Polyclonal Antibody (lower panel, Catalog # HAF1355) This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.Applications for Human Phospho-p53 (S37) Antibody

Background: p53
The p53 tumor suppressor protein acts to enforce cell cycle checkpoints or signal apoptosis in cells that have incurred genotoxic damage. The ATR and DNA-PKCS kinases phosphorylate p53 at serine 37 in response to UV light and other genotoxic stressors. This phosphorylation event results in increased p53 transcriptional activation.
