Immunohistochemistry click image to view larger	p53 in Human Breast Cancer Tissue. p53 phosphorylated at S46 was detected in immersion fixed paraffin-embedded sections of human breast cancer tissue using Rabbit Anti-Human Phospho-p53 (S46) Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1489) at 1.7 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Rabbit HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS005) and counterstained with hematoxylin (blue).

Western Blot click image to view larger	Detection of Human Phospho-p53 (S46) by Western Blot. Western blot shows lysates of MCF-7 human breast cancer cell line untreated (-) or treated (+) with 1 µM camptothecin (CPT) for 5 hours. PVDF membrane was probed with 1 µg/mL Rabbit Anti-Human Phospho-p53 (S46) Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1489) followed by HRP-conjugated Anti-Rabbit IgG Secondary Antibody (Catalog # HAF008). A specific band for Phospho-p53 (S46) 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 30 minutes. For additional reference the membrane was stripped and reprobed for total p53 using 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.

Simple Western lane view shows lysates of MCF‑7 human breast cancer cell line untreated (-) or treated (+) with 1 µM Camptothecin (CPT) for 5 hours, loaded at 0.2 mg/mL. A specific band was detected for Phospho-p53 (S46) at approximately 65 kDa (as indicated) using 10 µg/mL of Rabbit Anti-Human Phospho-p53 (S46) Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1489). This experiment was conducted under reducing conditions and using the 12-230 kDa separation system.
