Scientific Data Images for Human Phospho-p53 (S46) Antibody

Detection of Human Phospho-p53 (S46) antibody by Western Blot.

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.
p53 antibody in Human Breast Cancer Tissue by Immunohistochemistry (IHC-P).

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).

p53 antibody in Human Breast by Immunohistochemistry (IHC-P).

p53 in Human Breast.

p53 phosphorylated at S46 was detected in immersion fixed paraffin-embedded sections of human breast array using Rabbit Anti-Human Phospho-p53 (S46) Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1489) at 15 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).

Detection of Human Phospho-p53 (S46) antibody by Simple WesternTM.

Detection of Human Phospho-p53 (S46) by Simple WesternTM.

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.

Background: p53

The p53 tumor suppressor protein signals apoptosis in cells that have incurred irreparable genotoxic damage. Phosphorylation of p53 at serine 46 is a critical event leading to the cellular decision to undergo apoptosis rather than cell cycle arrest. Serine 46 can be phosphorylated by either the p38 MAP kinase or the homeodomain-interacting protein kinase 2 (HIPK2).
