XIAP (X-chromosome linked inhibitor of apoptosis) is a member of the apoptosis (IAP) family of proteins that inhibit caspases. The BIR2 domain of XIAP inhibits caspase-3 and caspase-7. The ability of XIAP to inhibit caspases is prevented by SMAC/Diablo through binding to XIAP-BIR2 and -BIR3 domains.

XIAP in Human Lymphoma.
XIAP was detected in immersion fixed paraffin-embedded sections of human lymphoma using 5 µg/mL Goat Anti-Human/Mouse/Rat XIAP Antigen Affinity-purified Polyclonal Antibody (Catalog # AF8221) overnight at 4 °C. Tissue was stained with the Anti-Goat HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS008) and counterstained with hematoxylin (blue).

Western blot shows lysates of Jurkat human acute T cell leukemia cell line, C2C12 mouse myoblast cell line, and PC-12 rat adrenal pheochromocytoma cell line. PVDF membrane was probed with 0.5 µg/mL of Goat Anti-Human/Mouse/Rat XIAP Antigen Affinity-purified Polyclonal Antibody (Catalog # AF8221) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF109). A specific band was detected for XIAP at approximately 56 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 4.Detection of Human and Mouse XIAP by Simple WesternTM.
Simple Western lane view shows lysates of Jurkat human acute T cell leukemia cell line and C2C12 mouse myoblast cell line, loaded at 0.2 mg/mL. A specific band was detected for XIAP at approximately 59 kDa (as indicated) using 5 µg/mL of Goat Anti-Human/Mouse/Rat XIAP Antigen Affinity-purified Polyclonal Antibody (Catalog # AF8221) followed by 1:50 dilution of HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF109). This experiment was conducted under reducing conditions and using the 12-230 kDa separation system.Western Blot Shows Human XIAP Specificity by Using Knockout Cell Line.
Western blot shows lysates of HeLa human cervical epithelial carcinoma parental cell line and XIAP knockout HeLa cell line (KO). PVDF membrane was probed with 0.5 µg/mL of Goat Anti-Human/Mouse/Rat XIAP Antigen Affinity-purified Polyclonal Antibody (Catalog # AF8221) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF017). A specific band was detected for XIAP at approximately 52 kDa (as indicated) in the parental HeLa cell line, but is not detectable in knockout HeLa cell line. GAPDH (Catalog # AF5718) is shown as a loading control. This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.Detection of Rat XIAP by Immunohistochemistry
Oxycodone differentially induces pro-and anti-apoptotic signaling in cell bodies and axons. a Immunohistochemical analysis of phospho-eIF2 alpha, ATF4, Bax, cleaved caspase 3 (Casp3), XIAP, and NF in striatum of rats treated with water (W) or oxycodone (O). Arrows point to axonal fascicles.
