Reagents for use in binding assays, particularly immunoassays, to determine diphenylhydantoin and for preparing reagents employed in such assays, including .beta.-galactosyl-umbelliferone-diphenylhydantoin conjugates, diphenylhydantoin immunogens, and N.sup.1, N.sup.3 and o-phenyl derivatives of diphenylhydantoin for preparing same. N.sup.1 and N.sup.3 -.omega.-aminoalkyl and o-(.omega.-aminoalkoxy)-phenyl derivatives are prepared and coupled by amide linkage to a .beta.-galactosyl-umbelliferone derivative to form labeled conjugates useful in homogeneous or heterogeneous binding assays. N.sup.1 and N.sup.3 -.omega.-carboxyalkyl and o-(.omega.-carboxyalkoxy)-phenyl derivatives are prepared and coupled by amide linkage to an immunogenic polyamino acid to form immunogen conjugates against which diphenylhydantoin-specific antibodies can be raised.
用于结合测定,特别是免疫测定,以确定二苯并噻嗪的试剂,以及用于制备这种测定中使用的试剂,包括β-半乳糖苷基-芹菜素-二苯并噻嗪共轭物、二苯并噻嗪免疫原和二苯并噻嗪的N1、N3和o-苯基衍生物,用于制备同类物。N1和N3-ω-氨基烷基和o-(ω-氨基烷氧基)-苯基衍生物通过酰胺键耦合到β-半乳糖苷基-芹菜素衍生物上,形成标记的共轭物,可用于均相或非均相结合测定。N1和N3-ω-羧基烷基和o-(ω-羧基烷氧基)-苯基衍生物通过酰胺键耦合到免疫原多氨基酸上,形成免疫原共轭物,可用于制备针对二苯并噻嗪特异性抗体。
