APAb ELISA kit applies the quantitative sandwich enzyme immunoassay technique. The microtiter plate has been pre-coated with Antiplatelet antigen (APAb). Standards or samples are then added to the microtiter plate wells and APAb if present, will bind to the antigen pre-coated wells. In order to quantitatively determine the amount of APAb present in the sample, a standardized preparation of horseradish peroxidase (HRP)-conjugated Antiplatelet antigen (APAb) are added to each well to sandwich th
