tcue792 ELISA Kit for Prothrombin Fragment 1+2 (F1+2)

The microplate provided in this kit has been pre-coated with an antibody specific to F1. Standards or samples are then added to the appropriate microplate wells with a biotin-conjugated antibody specific to F2. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain F1+2, biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm ± 10nm. The concentration of F1+2 in the samples is then determined by comparing the O.D. of the samples to the standard curve.
