WitrynaAbstract. Introduction: Immunosensors are affinity ligand-based biosensor solid-state devices in which the immunochemical reaction is coupled to a transducer. The … Witrynaamounts. In an immunochemical reaction , the unlabeled antigen competes with the conjugate for binding to a limited amount of antibody . Upon binding of the antibody to the conjugate enzyme, a conformational change in the enzyme associated with loss of activity may occur. The more unlabeled antigen in the sample, the more antibody china medical plastic molding
