Apoptosis is related to many diseases and induced by a family of cell death receptors and their ligands. Cell death signals are transduced by death domain (DD)-containing adapter molecules and members of the ICE/CED-3 protease family. Caspases-8 (FLICE) and -10 (FLICE2) are two pivotal members in the ICE/CED-3 protease family. FLICE-inhibitory proteins were identified in virus and human and designated v-FLIPs and c-FLIPs, respectively1,2. The human FLIPs were also cloned by several labs independently and termed Casper , I-FLICE, FLAME-1, CASH, CLARP and usurpin3-7. FLIP contains two death effector domains (DEDs) and a caspase-like domain. FLIP interacts with adapter protein FADD and caspase-8 and 0, and potently inhibits apoptosis induced by all known death receptors CD95, DR3, TRAIL-R and TNFR1. Four splice variants of c-FLIPs have been identified and termed FLIPa, b, g, and d, respectively. Applications: Suitable for use in Immunofluorescence, Western Blot and Immunocytochemistry. Other applications not tested. Recommended Dilution: Immunofluorescence: 2ug/ml Western Blot: 1:1000 Immunocytochemistry: 2ug/ml Optimal dilutions to be determined by the researcher. Positive Control: Total cell lysates. Storage and Stability: May be stored at 4 degrees C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20 degrees C. Aliquots are stable for at least 12 months. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
