• Preparation: Produced from sera of rabbits immunized with highly pure Recombinant Human sFas Receptor
• Anti-Human sFas Receptor-specific antibody was purified by affinity chromatography employing an immobilized Human sFas Receptor matrix
• Sandwich ELISA: To detect Human sFas Receptor by sandwich ELISA (using 100 μL/well antibody solution) a concentration of 0.5-2.0 μg/mL of this antibody is required
• This antigen affinity purified antibody, in conjunction with PeproTech Biotinylated Anti-Human sFas Receptor (500-P295Bt) as a detection antibody, allows the detection of at least 0.2-0.4 ng/well of Recombinant Human sFas Receptor
• Western Blot: To detect Human sFas Receptor by Western Blot analysis this antibody can be used at a concentration of 0.1-0.2 μg/mL
• When used in conjunction with compatible secondary reagents the detection limit for Recombinant Human sFas Receptor is 1.5-3.0 ng/lane, under either reducing or non-reducing conditions
• FAS (Fas, CD95, APO-1) is a 46 kDa transmembrane glycoprotein that functions as a cell death receptor of the TNFR (tumor necrosis factor receptor) superfamily
• FAS also exists in a soluble form that weight approximately 26kDa
• Stimulation of FAS results in aggregation of its intracellular FAS-associated death domains (FADD), formation of the death-inducing signaling complex (DISC) and activation of caspases
• The auto-proteolytic processing of the caspases in the complex trigger a downstream cascade that leads to apoptosis
• FAS has been shown to activate NF-kappaB, MAPK3/ERK1, MAPK8/JNK, and is involved in transducing the proliferating signals in normal diploid fibroblast and T cells
• At least eight alternatively spliced transcript variants encoding seven distinct isoforms have been described
• The isoforms lacking the transmembrane domain may negatively regulate the apoptosis mediated by the full-length isoform
• The Fas/Fas ligand system has been shown to play a role in a number of human diseases such as AIDS, hepatitis and cancer
• It is also assumed that induction of apoptosis through FAS ligand pathway is predominantly involved in anti-viral immune responses.
