The Human Fas Ligand (Hu FasL) ELISA quantitates Hu FasL in human serum, plasma, amniotic fluid, or cell culture medium. The assay will exclusively recognize both natural and recombinant Hu FasL.
Principle of the method
The Human FasL 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.
CD178 (Fas ligand, FasL) is a type-II-membrane protein, whose N-terminus is in the cytoplasm and its C-terminal region extends into the extracellular space. Its receptor, FasR, is a cell-surface-type-I-membrane protein and a member of the tumor necrosis factor (TNF) and nerve growth factor (NGF) receptor family. As a member of the TNF-cytokine family CD178 induces apoptosis when interacting with FasR. CD178 may exist as either membrane bound (45 kD) or soluble forms (26 kD). The soluble protein can be released from cells upon cleavage by metalloproteinases. Binding of CD178 to Fas leads to oligomerization of the receptor and triggers apoptotic cell death through the interaction of other proteins. CD178 is predominantly expressed in activated T-lymphocytes and natural killer (NK) cells also it is expressed in the tissues of immune-privilege sites such as testis and eye. CD178 expression is also reported in various tissues as thymus, liver, ovary, lung, heart and kidney. It is assumed that induction of apoptosis through CD178 is predominantly involved in anti-viral immune responses. CD178 is a cell surface molecule belonging to the tumor necrosis factor family, binds to its receptor Fas, thus inducing apoptosis. Various cells express FAS, where CD178 is expressed predominantly on activated T cells. FAS and CD178 are involved in the down-regulation of immune reactions as well as T cell-mediated cytotoxicity. CD178 concentration has also been shown to be associated with atherosclerosis and inflammatory disease, in patients with hypertension. The Fas/ CD178 system has been shown to play a role in a number of human diseases, for example AIDS, hepatitis or cancer.
