anti-Asc, pAb (AL177)
Total protein extracts from various human (293-T, Jurkat, Raj, Ramos, BJAB, THP-1, U937, K562, Raw, HeLa) and mouse (EL-4, A20) cell lines were run on SDS-PAGE and Pycard detected by anti-Asc, pAb (AL177) at 1:1’000 dilution. Anti-rabbit IgG coupled horse radish peroxidase was used at 1:5’000 dilution for ECL detection.

Scientific Background Information
Asc promotes caspase-mediated apoptosis. This proapoptotic activity is mediated predominantly through the activation of caspase-9. It is a component of the inflammasome, a protein complex which also includes NLRP3/NALP3, CARD8 and CASP1 and whose function is the activation of proinflammatory caspases.
