Abstract
Abstract CATECHOLAMINE ANTIGENS ARE PREPARD BY COUPLING CATECHOLAMINE HAPTENS TO IMMUNOGENIC CARRIER MATERIALS. IN PREFERRED EMBODIMENTS, PROTEINS OR POLYPEPTIDES ARE USED AS CARRIER MATERIALS. THE ANTIGENS RODUCE IMMUNOLOGICAL EFFECTS WHEN INJECTED INTO HOST ANIMALS, INCLUDING THE FORMATION OF ANTICATECHOLAMINE ANTIBODIES. THESE RESULTING ANTIBODIES ARE USEFUL IN BIONANLYTICAL TECHNIQUES FOR THE DETRMINATION OF CATECHOLAMINE BASED ACTIVITY IN BIOLOGICAL SYSTEMS.
