Detection of Human Phospho-p53 (S392) by Western Blot. Western blot shows lysates of MCF-7 human breast cancer cell line untreated (-) or treated (+) with 1uM Camptothecin (CPT) for 5 hours. PVDF membrane was probed with 2 µg/mL of Rabbit Anti-Human Phospho-p53 (S392) Monoclonal Antibody (Catalog # MAB2996) followed by HRP-conjugated Anti-Rabbit IgG Secondary Antibody (Catalog # HAF008). A specific band was detected for Phospho-p53 (S392) at approximately 53 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Phospho-p53 (S392) in MCF‑7 Human Cell Line. p53 phosphorylated at S392 was detected in immersion fixed MCF-7 human breast cancer cell line using Rabbit Anti-Human Phospho-p53 (S392) Monoclonal Antibody (Catalog # MAB2996) at 3 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Rabbit IgG Secondary Antibody (red; Catalog # NL004) and counterstained with DAPI (blue). Specific staining was localized to cytoplasm and nuclei. View our protocol for Fluorescent ICC Staining of Cells on Coverslips.

Background: p53

The p53 tumor suppressor protein acts to enforce cell cycle checkpoints or signal apoptosis in cells that have incurred genotoxic damage. The ATM or ATR kinases can phosphorylate p53 at serine 15 (S15), which leads to cell cycle arrest. Serine 15 phosphorylation leads to p53 stabilization and enhances transactivation of p53 target genes.
