Product Info
Background FAS/APO-1 (CD95) is an important member of the tumor necrosis factor (TNF) superfamily involved in membrane-mediated apoptosis. Ligation of Fas by FAS ligand or an anti-FAS cross-linking antibody, triggers activation of the caspase cascade (1). Functional impairment of the FAS/FAS-L system is associated with the development and progression of malignancies (2). FAS gene mutations have been suggested to have a role in testicular germ cell tumors (3). Tumor cells frequently exhibit de novo expression of FAS-ligand (FAS-L), which plays a significant role in local tissue destruction, metastatic spread, and immune escape of the tumor cells (8). The apoptosis of lymphocytes, which occurs in autoimmune diseases, is usually induced by the FAS/FAS-ligand system (7). FAS is believed to be involved in various autoimmune diseases including, ulcerative colitis, Graves disease, and rheumatoid arthritis (5,7). FAS expression on gastric epithelial cells in patients infected with H. Pylori is responsible for the accelerated apoptosis of the cells (4). Serum FAS-L concentration has also been shown to be associated with atherosclerosis and inflammatory disease, in patients with hypertension (6). 
Origin FAS-L (A19) is provided as an affinity purified rabbit polyclonal antibody, raised against a peptide mapping near the amino terminus of rat FAS-L.
