Western blot analysis was performed on whole cell extracts (30 ug lysate) of Jurkat (Lane 1), Jurkat treated for overnight with 3 uM of Staurosporine (Lane 2), HeLa (Lane 3), HeLa treated for overnight with 3 uM of Staurosporine (lane 4), A549 (lane 5), PC-3 (lane 6) and MDA-MB-231 (lane 7). The blots were probed with Anti-Caspase 8 Mouse Monoclonal Antibody (Product# MA511558, 2-4 ug/ml) and detected by chemiluminescence using Goat anti-Mouse IgG (H+L) Secondary Antibody, HRP conjugate (Product # 626520, 1:4000 dilution). A 55 kDa band corresponding to Caspase 8 was observed across cell lines tested except Staurosporine treated lysates. Known quantity of protein samples were electrophoresed using Novex® NuPAGE® 10 % Bis-Tris gel (Product # NP0302BOX), XCell SureLock™ Electrophoresis System (Product # EI0002) and Novex® Sharp Pre-Stained Protein Standard (Product # LC5800). Resolved proteins were then transferred onto a nitrocellulose membrane with iBlot® 2 Dry Blotting System (Product # IB21001). The membrane was probed with the relevant primary and secondary Antibody using iBind™ Flex Western Starter Kit (Product# SLF2000S). Chemiluminescent detection was performed using Novex® ECL Chemiluminescent Substrate Reagent Kit (Product # WP20005).

MA5-11558 targets Caspase 8 in IP and WB applications and shows reactivity with Human samples.
The MA5-11558 immunogen is recombinant full length human Caspase 8 protein.
Caspase 8 binds to the death effector domain (DED) of FADD through an analogous DED domain present in tandem in the proform of the caspase 8 protein. Recruitment of caspase 8 to the Fas receptor results in oligomerization of the caspase 8 protein, which in turn drives its autoactivation through "self-cleavage". Activated caspase 8 then activates other downstream caspases including caspase 9, thereby commiting the cell to undergo apoptosis.
