Application Notes

Applications Validated by Active Motif:
WB: 1 - 2 µg/ml dilution

For optimal results, primary antibody incubations should be performed at room temperature. The addition of 0.1% Tween 20 to all blocking solutions may also reduce background. Individual optimization may be required.


This Caspase-8 antibody was raised against a synthetic peptide corresponding to amino acid residues 217-222 of human Caspase-8.


PBS containing 0.02% sodium azide. Sodium azide is highly toxic.


Caspase-8 mAb tested by Western blot.
Caspase-8 detection by Western blot. The analysis was performed using Jurkat extracts with Caspase-8 mAb at 2 µg/ml (lane 1) and 0.5 µg/ml (lane 2) dilutions. The antibody only detects 55 kDa caspase-8 in staurosporine-treated (2 hours) Jurkat cells.


Caspase-8 (CASP8 or apoptosis-related cysteine peptidase 8) is the most upstream protease of the activation cascade of caspases responsible for the TNFRSF6/FAS mediated and TNFRSF1A induced cell death. Binding to the adaptor molecule FADD recruits it to either receptor. Caspase-8 cleaves and activates Caspase-3, Caspase-4, Caspase-6, Caspase-7, Caspase-9 and Caspase-10.


Some products may be shipped at room temperature. This will not affect their stability or performance. Avoid repeated freeze/thaw cycles by aliquoting items into single-use fractions for storage at -20°C for up to 2 years. Keep all reagents on ice when not in storage.
