Scientific Data Images for Human XIAP Antibody

XIAP antibody in Human Brain by Immunohistochemistry (IHC-P).

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).

Neutralization of XIAP Activity by Human XIAP Antibody.

Neutralization of XIAP Activity by Human XIAP Antibody.

Recombinant Human Caspase-7 (0.012 µg/mL, Catalog # 823-C7) activity is measured in the presence of Recombinant Human XIAP (2.75 µg/mL, Catalog # 822-XF) that has been preincubated with increasing concentrations of Mouse Anti-Human XIAP Antibody (Catalog # MAB8221) The ND50 is typically 10 µg/mL.

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.

Long Name
