Methods employing thyroid analog conjugates to enzymes and to immunogenic carriers are provided, which find use in the determination of thyroid compounds normally in physiological fluids, such as serum. The immunogenic carrier conjugates are used to raise antibodies specific to thyroid compounds. The antibodies and enzyme conjugates are used in assays for thyroid compounds. The thyroid analogs are characterized by the presence of only one phenyl ring that contains a hydroxyl substituent and one or two substituents in an ortho relationship to the hydroxyl substituent on the phenyl ring wherein the phenyl ring is conjugated to an enzyme or an immunogenic carrier by a bond or a linking group. Kits for conducting the methods of the present invention are also disclosed.
本发明提供了使用甲状腺类似物结合酶和免疫原载体的方法,这些方法在测定生理液体(如血清)中通常存在的甲状腺化合物方面有用。免疫原载体结合物被用于产生特异性甲状腺化合物的
抗体。这些
抗体和酶结合物被用于测定甲状腺化合物。甲状腺类似物的特征在于仅存在一个苯环,其中含有一个羟基取代基和一个或两个取代基与苯环上羟基取代基的正交关系,其中苯环通过键或连接基与酶或免疫原载体结合。本发明还公开了用于进行本发明方法的试剂盒。
