Abcam’s Soluble TNF Receptor II ELISA (Enzyme-Linked Immunosorbent Assay) kit is an in vitro enzyme-linked immunosorbent assay for the quantitative measurement of Human Soluble TNF Receptor II in serum, plasma and cell culture supernatants.
This assay employs an antibody specific for Human Soluble TNF Receptor II coated on a 96-well plate. Standards and samples are pipetted into the wells and Soluble TNF Receptor II present in a sample is bound to the wells by the immobilized antibody. The wells are washed and biotinylated anti-Human Soluble TNF Receptor II antibody is added. After washing away unbound biotinylated antibody, HRP-conjugated streptavidin is pipetted to the wells. The wells are again washed, a TMB substrate solution is added to the wells and color develops in proportion to the amount of Soluble TNF Receptor II bound. The Stop Solution changes the color from blue to yellow, and the intensity of the color is measured at 450 nm.
Optimization may be required with urine samples.
Storage instructionsStore at -20°C. Please refer to protocols.

RelevanceTNFRII (TNF Receptor II) is a member of the TNFR family of transmembrane proteins, and is expressed in immune cells and certain endothelial cells. It is a high affinity receptor for TNF alpha but manifests a lower affinity to TNF beta. Signaling through this receptor regulates various biological processes including cell proliferation, differentiation, apoptosis, lipid metabolism, coagulation, and neurotransmission. TNFRII consists of a 240 amino acid residue extracellular ligand binding portion, a 27 amino acid residue transmembrane segment and a 173 amino acid residue cytoplasmic domain. Soluble TNFRII (Soluble TNF Receptor II) is a 268 amino acid isoform containing the extracellular ligand-binding portion of TNFRII. It binds to TNF alpha and is capable of inhibiting TNF alpha induced activities by acting as a decoy receptor.
