KE10065 is a solid phase sandwich Enzyme Linked-Immuno-Sorbent Assay (Sandwich ELISA). The MouseTNFR1 ELISA kit is to be used to detect and quantify protein levels of endogenous mouseTNFR1. The assay recognizes mouseTNFR1. An antibody specific for mouseTNFR1 has been pre-coated onto the microwells. The mouseTNFR1 protein in samples is captured by the coated antibody after incubation. Following extensive washing, another antibody of biotinylated specific for mouseTNFR1 is added to detect the captured mouseTNFR1 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.
