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 to enforce cell cycle arrest. Serine 15 phosphorylation leads to p53 stabilization and enhances transactivation of p53 target genes.

Scientific Data Images for Human Phospho-p53 (S15) Antibody
Detection of Phospho-p53 in camptothecin-treated MCF‑7 Human Cell Line by Flow Cytometry.
MCF-7 human breast cancer cell line was unstimulated (light orange filled histogram) or treated with 1 µM camptothecin for 6 hours (dark orange filled histogram), then stained with Mouse Anti-Human Phospho-p53 (S15) Monoclonal Antibody (Catalog # MAB18391) or isotype control (Catalog # MAB002, open histogram), followed by Phycoerythrin-conjugated Anti-Mouse IgG F(ab')2Secondary Antibody (Catalog # F0102B). To facilitate intracellular staining, cells were fixed with paraformaldehyde and permeabilized with saponin.Applications for Human Phospho-p53 (S15) Antibody
