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 (
