Principiul testului

Human CEA ELISA Kit (A334862) employs a one-step sandwich enzyme-linked immunosorbent assay (ELISA) for the quantitative determination of human CEA in serum, plasma, and cell culture supernatant. A 96-well microtiter plate is provided pre-coated with an antibody specific for CEA. Standards and test samples are added to the wells, allowing CEA 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 CEA captured in each well. The concentration of CEA is determined by measuring absorbance at 450 nm and interpolating from the standard curve.
