Description

The Human TNF-Related-Apoptosis-Inducing-Ligand (Hu TRAIL) ELISA quantitates Hu TRAIL in human serum, plasma, buffered solution, or cell culture medium. The assay will exclusively recognize both natural and recombinant Hu TRAIL. Principle of the method The Human TRAIL 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.

TRAIL is a cytokine that belongs to the tumor necrosis factor (TNF) ligand family. TRAIL preferentially induces apoptosis in transformed and tumor cells, but does not appear to kill normal cells although it is expressed at a significant level in most normal tissues. TRAIL binds to several members of TNF receptor superfamily including TNFRSF10A/TRAILR1, TNFRSF10B/TRAILR2, TNFRSF10C/TRAILR3, TNFRSF10D/TRAILR4, and possibly also to TNFRSF11B/OPG. The activity of this protein may be modulated by binding to the decoy receptors TNFRSF10C/TRAILR3, TNFRSF10D/TRAILR4, and TNFRSF11B/OPG that cannot induce apoptosis. The binding of TRAIL protein to its receptors has been shown to trigger the activation of MAPK8/JNK, caspase 8, and caspase 3. Receptors for TRAIL include two death domain containing receptors, death receptor 4 (DR4) and DR5, as well as two decoy receptors, DcR1 and DcR2, lacking the intracellular signaling death domain. TRAIL is a type II membrane protein and expressed in a variety of human tissues. Like TNF and Fas ligand, TRAIL induces apoptosis and NF-kB activation in many tissues and cells.
