MDM2 in Mouse Kidney. MDM2 was detected in perfusion fixed frozen sections of mouse kidney using Human/Mouse/Rat MDM2 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1244) at 5 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 MDM2 by Western Blot. Western blot shows lysates of U2OS human osteosarcoma cell line, MCF‑7 human breast cancer cell line, and CEM human T‑lymphoblastoid cell line untreated (-) or treated (+) with 5 μM LLnV for 1 hour. PVDF membrane was probed with 1 µg/mL of Human/Mouse/Rat MDM2 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1244), followed by HRP-conjugated Anti-Rabbit IgG Secondary Antibody (Catalog # HAF008). A specific band was detected for MDM2 at approximately 95 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

MDM2 is a key regulator of p53 tumor suppressor protein activity and stability. MDM2 binds to and inhibits the transactivation domain of p53. In addition, MDM2 controls p53 stability by functioning as its E3 ligase in ubiquitination and by shuttling p53 from the nucleus to the cytoplasm for subsequent degradation. The importance of the p53/MDM2 relationship is underscored by the existence of an autoregulatory feedback loop whereby activated p53 transcriptionally up‑regulates the expression of its own inhibitor, MDM2.
