FAF1 (Fas-associated protein factor 1) specifically interacts with the cytoplasmic domain of wild type, but not mutated, Fas in both yeast and mammalian cells. When transiently expressed in T cells, FAF1 potentiates Fas-induced apoptosis. In contrast to TRADD, FADD, and RIP, FAF1 lacks a DDH (Death domain homologous region) and cannot induce apoptosis independent of Fas activation.
Applications

Storage and Stability
Store product at 4°C if to be used immediately within two weeks. For long-term storage, aliquot to avoid repeated freezing and thawing and store at -20°C. Aliquots are stable at -20°C for 12 months after receipt. Dilute required amount only prior to immediate use. Further dilutions can be made in assay buffer. Note: Sodium azide is a potent inhibitor of peroxidase and should not be added to HRP conjugates. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
Note: Applications are based on unconjugated antibody.
