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.
用于结合测定的试剂,特别是免疫测定,以确定二苯并噻嗪,并用于制备用于这种测定的试剂,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,用于制备同类或异类结合测定的标记共轭物。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偶联到β-半乳糖苷基-芹菜素衍生物上形成标记共轭物,可用于同质或异质结合测定。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偶联到免疫原多氨基酸上形成免疫原共轭物,可制备出针对二苯并噻嗪特异性抗体的免疫原共轭物。
