In the field of cell biology, TNF-related apoptosis-inducing ligand(TRAIL), is a protein which functions as a ligand which induces the process of cell death called apoptosis. TRAIL has also been designated CD253(cluster of differentiation 253).Tumor necrosis factor(TNF) family cytokines function as prominent mediators of immune regulation and the inflammatory response. Most TNF family cytokines are expressed as type II transmembrane proteins, with homology confined to approximately 150 C-terminal residues. The TNF ligands interact with a parallel family of receptors. TRAIL binds to the death receptors DR4(TRAIL-RI) and DR5(TRAIL-RII). The process of apoptosis is caspase-8-dependent. Caspase-8 activates downstream effector caspases including procaspase-3, -6, and -7, leading to activation of specific kinases. TRAIL also binds the receptors DcR1 and DcR2, which do not contain a cytoplasmic domain(DcR1) or contain a truncated death domain(DcR2). The standard product used in this kit is recombinant human TRAIL with the molecular mass of 21KDa. It is expressed from the amino acids ectoderm T95--G28.

Useful in Sandwich ELISA for Quantitative Detection of Antigen. Aliquot 0.1ml per well of the 1000pg/ml, 500pg/ml, 250pg/ml, 125pg/ml, 62.5pg/ml, 31.2pg/ml, 15.6pg/ml human TRAIL standard solutions into the precoated 96-well plate. Add 0.1ml of the sample diluent buffer into the control well (Zero well). Add 0.1ml of each properly diluted sample of human cell culture supernates, cell lysates, serum, plasma(heparin, EDTA) or saliva to each empty well. It is recommended that each human TRAIL standard solution and each sample be measured in duplicate.
