Clonality Monoclonal
Clone Names E7
Calculated MW 55391 Da
Gene ID 841
Other Names Caspase-8, CASP-8, Apoptotic cysteine protease, Apoptotic protease Mch-5, CAP4, FADD-homologous ICE/ced-3-like protease, FADD-like ICE, FLICE, ICE-like apoptotic protease 5, MORT1-associated ced-3 homolog, MACH, Caspase-8 subunit p18, Caspase-8 subunit p10, CASP8, MCH5
Target/Specificity A synthetic peptide corresponding to N-terminal residues of human Caspase-8 subunit p18 was used as immunogen. The antibody should recognize both pro-form (55kDa) and p18 cleaved-form of Caspase-8.
Dilution WB~~1:500
Format 50 mM Tris-Glycine (pH 7.4), 0.15 M NaCl, 40% Glycerol, 0.01% sodium azide and 0.05% BSA.
StorageMaintain refrigerated at 2-8°C for up to 6 months. For long term storage store at -20°C in small aliquots to prevent freeze-thaw cycles.
PrecautionsCaspase-8 Antibody is for research use only and not for use in diagnostic or therapeutic procedures.
Protein Information
Name CASP8
Synonyms MCH5
Function Most upstream protease of the activation cascade of caspases responsible for the TNFRSF6/FAS mediated and TNFRSF1A induced cell death. Binding to the adapter molecule FADD recruits it to either receptor. The resulting aggregate called death- inducing signaling complex (DISC) performs CASP8 proteolytic activation. The active dimeric enzyme is then liberated from the DISC and free to activate downstream apoptotic proteases. Proteolytic fragments of the N-terminal propeptide (termed CAP3, CAP5 and CAP6) are likely retained in the DISC. Cleaves and activates CASP3, CASP4, CASP6, CASP7, CASP9 and CASP10. May participate in the GZMB apoptotic pathways. Cleaves ADPRT. Hydrolyzes the small-molecule substrate, Ac-Asp-Glu-Val-Asp-|-AMC. Likely target for the cowpox virus CRMA death inhibitory protein. Isoform 5, isoform 6, isoform 7 and isoform 8 lack the catalytic site and may interfere with the pro-apoptotic activity of the complex.
Cellular Location Cytoplasm.
Tissue Location Isoform 1, isoform 5 and isoform 7 are expressed in a wide variety of tissues. Highest expression in peripheral blood leukocytes, spleen, thymus and liver. Barely detectable in brain, testis and skeletal muscle

Caspase-8 (MACH/FLICE/Mch5) is a member of a family of cysteine-requiring aspartate proteases that participate in the intracellular signaling cascade leading to apoptosis, or programmed cell death (1-4). Caspase-8 is recruited to death-inducing signaling complex (DISC) CD95 (Fas/APO-1) and tumor necrosis factor receptor 1 (TNFR1) and is subsequently activated by proteolytic cleavage into two residues, p10 and p18 (1-4). Active caspase-8, the first in the caspase signaling cascade, signals downstream caspases to eventually induce apoptosis.
