Product Information
KE00051 is a solid phase sandwich Enzyme Linked-Immuno-Sorbent Assay (Sandwich ELISA). The TNFR1 ELISA kit is to be used to detect and quantify protein levels of endogenous TNFR1. The assay recognizes human TNFR1. An antibody specific for TNFR1 has been pre-coated onto the microwells. The TNFR1 protein in samples is captured by the coated antibody after incubation. Following extensive washing, another antibody of biotinylated specific for TNFR1 is added to detect the captured TNFR1 protein. For signal development, Streptavidin-HRP is added, followed by Tetramethyl-benzidine (TMB) reagent. Solution containing sulfuric acid is used to stop color development and the color intensity which is proportional to the quantity of bound protein is measurable at 450 nm with the correction wavelength set at 630 nm.

Background Information
Tumor necrosis factor (TNF) is a multifunctional cytokine that plays a key role in regulating inflammation, immune functions, host defense, and apoptosis. TNF signals through two distinct cell surface receptors, TNFR1 (TNFRSF1A, CD120a) and TNFR2 (TNFRSF1B, CD120b). TNFR1, which contains a death domain (DD) within its intracytoplasmic region, is thought to be the key receptor for TNF signaling. This receptor can be released to the extracellular space by two mechanisms, ectodomain shedding and constitutive release of full-length 55-kDa TNFR1. Soluble TNFR1 (sTNFR1) could function as TNF-binding protein, inhibiting TNF bioactivity. This ELISA kit can be used to measure natural and recombinant human sTNFR1.
