About This Kit
The Human Soluble APO-1/Fas ELISA quantitates Hu sAPO-1/Fas in human serum, or cell culture medium. The assay will exclusively recognize both natural and recombinant Hu sAPO-1/Fas.
Principle of the method
The Human APO-1/Fas solid-phase sandwich ELISA (enzyme-linked immunosorbent assay) is designed to measure the amount of the target bound between a matched antibody pair. A target-specific antibody has been pre-coated in the wells of the supplied microplate. Samples, standards, or controls are then added into these wells and bind to the immobilized (capture) antibody. The sandwich is formed by the addition of the second (detector) antibody, a substrate solution is added that reacts with the enzyme-antibody-target complex to produce measurable signal. The intensity of this signal is directly proportional to the concentration of target present in the original specimen.
Rigorous validation
Each manufactured lot of this ELISA kit is quality tested for criteria such as sensitivity, specificity, precision, and lot-to-lot consistency. See manual for more information on validation.
Target information
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.
