Western blot shows lysates of MCF-7 human breast cancer cell line mock-treated (-) or treated (+) with 1 μM camptothecin (CPT) for 1 hour. Human p53 was immunoprecipitated using Mouse Anti-Human/Mouse/Rat p53 Monoclonal Antibody (Catalog # MAB1355). PVDF membrane was probed with HRP-conjugated Anti-Human/Mouse/Rat Polyclonal Antibody (Catalog # HAF1355). A specific band for p53 was detected at approximately 53 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.
p53 was detected in immersion fixed HeLa human cervical epithelial carcinoma cell line using Mouse Anti-Human/Mouse/Rat p53 Monoclonal Antibody (Catalog # MAB1355) at 3 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Mouse IgG Secondary Antibody (red; Catalog # NL007) and counterstained with DAPI (blue). Specific staining was localized to cytoplasm and nuclei. View our protocol for Fluorescent ICC Staining of Cells on Coverslips.

The p53 tumor suppressor protein is a multi-functional transcription factor that regulates cellular decisions regarding proliferation, cell cycle checkpoints, and apoptosis. The importance of p53 is underscored by its mutation in over 50% of human cancers. Mice that lack one or both copies of p53 also showed an increased incidence of tumors, which makes the p53 deficient mouse a model system for studying cancer generation and progression.
