Scientific Data

Western Blot Detection of Human cIAP-1/HIAP-2 antibody by Western Blot. View Larger

Detection of Human cIAP-1/HIAP-2 by Western Blot. Western blot shows lysates of HEK293 human embryonic kidney cell line either mock transfected, transfected with full length human cIAP-1, or transfected with full length human cIAP-2, HepG2 human hepatocellular carcinoma cell line, Jurkat human acute T cell leukemia cell line, and A431 human epithelial carcinoma cell line. PVDF Membrane was probed with 1 µg/mL of Human cIAP-1/HIAP-2 Monoclonal Antibody (Catalog # MAB818) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). A specific band was detected for cIAP-1/HIAP-2 at approximately 72 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 2.

Detection of Human cIAP‑1/HIAP‑2 by Simple WesternTM. Simple Western lane view shows lysates of HepG2 human hepatocellular carcinoma cell line, loaded at 0.2 mg/mL. A specific band was detected for cIAP‑1/HIAP‑2 at approximately 66 kDa (as indicated) using 5 µg/mL of Mouse Anti-Human cIAP‑1/HIAP‑2 Monoclonal Antibody (Catalog # MAB818). This experiment was conducted under reducing conditions and using the 12-230 kDa separation system.

Western Blot Shows Human cIAP-1/HIAP-2 Specificity by Using Knockout Cell Line. Western blot shows lysates of HeLa human cervical epithelial carcinoma parental cell line and cIAP-1/HIAP-2 knockout HeLa cell line (KO). PVDF membrane was probed with 1 µg/mL of Mouse Anti-Human cIAP-1/HIAP-2 Monoclonal Antibody (Catalog # MAB818) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF018). A specific band was detected for cIAP-1/HIAP-2 at approximately 68 kDa (as indicated) in the parental HeLa cell line, but is not detectable in knockout HeLa cell line. GAPDH (Catalog # MAB5718) is shown as a loading control. This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Background: cIAP-1/HIAP-2

cIAP-1 (also known as BIR2, MIHB and HIAP-2) is a member of the inhibitor of apoptosis (IAP) family of proteins that inhibit the proteolytic activity of mature caspases. cIAP-1 has 3 BIR (baculovirus inhibitor of apoptosis) domains, a RING finger domain, and a caspase recruitment domain (CARD). cIAP-1 inhibits caspases by interaction of the BIR domain with the active caspase. Caspase activity may be restored through interactions with the Reaper like motif on mitochondrial proteins such as SMAC/Diablo or HTRA-2/Omi. cIAP-1 is reported to be cleaved by caspases in fetal rat hepatocytes treated with TGF-beta.
