Principiul testului

Human TNF alpha ELISA Kit (High Sensitivty) (A334800) employs a one-step sandwich enzyme-linked immunosorbent assay (ELISA) for the quantitative determination of human TNF alpha in serum, plasma, and cell culture supernatant. A 96-well microtiter plate is provided pre-coated with an antibody specific for TNF alpha. Standards and test samples are added to the wells, allowing TNF alpha to bind to the immobilized capture antibody. A prepared antibody mixture is added and incubated to form antibody–antigen complexes. After incubation, unbound material is removed by washing, and TMB substrate is added to develop colour through an HRP-catalysed reaction. The reaction is stopped with acidic stop solution, producing a yellow endpoint signal. The intensity of the colour is proportional to the amount of TNF alpha captured in each well. The concentration of TNF alpha is determined by measuring absorbance at 450 nm and interpolating from the standard curve.
