Scientific Data

Western Blot Detection of Human A20/TNFAIP3 antibody by Western Blot. View Larger

Detection of Human A20/TNFAIP3 by Western Blot. Western blot shows lysates of HepG2 human hepatocellular carcinoma cell line and NCI-H460 human large cell lung carcinoma cell line. PVDF membrane was probed with 2 µg/mL of Mouse Anti-Human A20/TNFAIP3 Monoclonal Antibody (Catalog # MAB7598) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (HAF018). A specific band was detected for A20/TNFAIP3 at approximately 95 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Detection of A20/TNFAIP3 in Human Colon. A20/TNFAIP3 was detected in immersion fixed paraffin-embedded sections of Human Colon using Mouse Anti-Human A20/TNFAIP3 Monoclonal Antibody (Catalog # MAB7598) at 5 µg/mL for 1 hour at room temperature followed by incubation with the Anti-Mouse IgG VisUCyte™ HRP Polymer Antibody (Catalog # VC001). Before incubation with the primary antibody, tissue was subjected to heat-induced epitope retrieval using VisUCyte Antigen Retrieval Reagent-Basic (Catalog # VCTS021). Tissue was stained using DAB (brown) and counterstained with hematoxylin (blue). Specific staining was localized to cytoplasm in epithelial cells in mucosal glands.

Background: A20/TNFAIP3

A20 (TNF alpha -induced protein 3) is a cytoplasmic zinc finger protein that inhibits NF kappa B activity and tumor necrosis factor-mediated programmed cell death. The protein interacts with NAF1 and inhibits TNF-induced NF kappa B-dependent gene expression by interfering with RIP- or TRAF2-mediated transactivation signaling. A20 contains an N-terminal domain which has deubiquitinating enzyme activity and removes ubiquitin chains from receptor-interacting protein (RIP), thus mediating distinct regulatory effects in the down-regulation of NF kappa B signaling.
