| 测试原理 | This ELISA kit uses the Sandwich-ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with an antibody specific to Human SCCA1. Samples (or Standards) and Horseradish Peroxidase (HRP) linked antibody specific for Human SCCA1 are added to the micro ELISA plate wells. Human SCCA1 in samples (or standards) combines with the coated antibody and HRP linked detection antibody special to Human SCCA1. Excess conjugate and unbound sample or standard are washed from the plate. The substrate solution is added to each well. The enzyme-substrate reaction is terminated by the addition of stop solution and the color turns yellow. The optical density (OD) is measured spectrophotometrically at a wavelength of 450±2 nm. The OD value is proportional to the concentration of Human SCCA1. The concentration of Human SCCA1 in the samples is then determined by comparing the OD of the samples to the standard curve. | ||
