PeproTech FAS (soluble) Polyclonal Antibody, Biotin, PeproTech®, Invitrogen™ 

Description

AA Sequence of recombinant protein: MRLSSKSVNA QVTDINSKGL ELRKTVTTVE TQNLEGLHHD GQFCHKPCPP GERKARDCTV NGDEPDCVPC QEGKEYTDKA HFSSKCRRCR LCDEGHGLEV EINCTRTQNT KCRCKPNFFC NSTVCEHCDP CTKCEHGIIK ECTLTSNTKC KEEGSRS. 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 and then biotinylated. Sandwich ELISA: To detect Human sFas Receptor by sandwich ELISA (using 100 mL/well) a concentration of 0.25-1.0 μg/mL of this antibody is required. This biotinylated polyclonal antibody, in conjunction with PeproTech Polyclonal Anti- Human sFas Receptor (500-P295) as a capture 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 mg/mL. When used in conjunction with compatible development reagents the detection limit for Recombinant Human sFas Receptor is 1.5-3.0 ng/lane, under either reducing or non-reducing conditions. 500-P295BT-1MG will be provided as 2 x 500 μg

CD95, also known as Fas or APO-1, is a 46 kDa transmembrane glycoprotein that functions as a cell death receptor in the tumor necrosis factor receptor (TNFR) superfamily. It is expressed by a wide range of hematopoietic and non-hematopoietic cells, including monocytes, neutrophils, lymphocytes, and fibroblasts. CD95 also exists in a soluble form weighing approximately 26 kDa. The interaction of CD95 with its ligand, FasL, induces apoptosis, playing a crucial role in peripheral tolerance and anti-viral immune responses. Upon stimulation, CD95 leads to the aggregation of its intracellular Fas-associated death domains (FADD), formation of the death-inducing signaling complex (DISC), and activation of caspases. This cascade results in apoptosis. CD95 is also involved in activating NF-kappaB, MAPK3/ERK1, and MAPK8/JNK, and transduces proliferative signals in normal diploid fibroblasts and T cells. There are at least eight alternatively spliced transcript variants encoding seven distinct isoforms of CD95. Isoforms lacking the transmembrane domain may negatively regulate apoptosis mediated by the full-length isoform. The Fas/Fas ligand system is implicated in several human diseases, including AIDS, hepatitis, and cancer, highlighting its importance in immune regulation and disease pathology.
