Human XIAP Antibody Summary

Species Reactivity
Detects human XIAP in direct ELISAs. In direct ELISAs, no cross-reactivity with recombinant human (rh) cIAP-1 or rh cIAP-2 is observed. Neutralizes human XIAP and human XIAP-BIR2 bioactivity. Does not neutralize XIAP-BIR3 or Livin bioactivity.
Monoclonal Mouse IgG1 Clone # 117318
Protein A or G purified from hybridoma culture supernatant
E. coli-derived recombinant human XIAP
Accession # P98170
Lyophilized from a 0.2 μm filtered solution in PBS with Trehalose. *Small pack size (SP) is supplied either lyophilized or as a 0.2 µm filtered solution in PBS.


Recommended Concentration
8-25 µg/mL
See below
Measured by its ability to neutralize Recombinant Human XIAP (2.75 µg/mL, Catalog # 822-XF) inhibition of Recombinant Human Caspase‑7 (0.012 µg/mL, Catalog # 823-C7) cleavage of the fluorogenic peptide substrate DEVD-AFC (50 µM). The Neutralization Dose (ND50) is typically 10 µg/mL.

Please Note: Optimal dilutions should be determined by each laboratory for each application. General Protocols are available in the Technical Information section on our website.

Scientific Data

XIAP in Human Brain. XIAP was detected in immersion fixed paraffin-embedded sections of human brain (cortex) using 25 µg/mL Mouse Anti-Human XIAP Monoclonal Antibody (Catalog # MAB8221) overnight at 4 °C. Tissue was stained with the Anti-Mouse HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS002) and counter-stained with hematoxylin (blue).

Background: XIAP

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.
