В реакции N-сукцинимидного эфира 6-(О-карбоксиметил)оксима 24-эпикастастерона с европиевой солью N1-(аминоэтил)амида диэтилентриаминпентауксусной кислоты синтезирован низкомолекулярный конъюгат брассиностероид-комплексонат Eu3+. Продуктом одновременного ацилирования первичных аминогрупп полипептидной цепи альбумина активированными эфирами карбоксипроизводных 24-эпикастастерона и комплексоната Eu3+ является белковый конъюгат, обладающий высокой удельной флуоресцентной активностью. При использовании высокомолекулярного конъюгата в иммунохимической системе получена линейная зависимость флуоресцентного сигнала меченого 24-эпикастастерона, связанного с иммобилизованными антителами, от концентрации 24-эпибрассинолида (1–300 нМ) в растворе.</p></abstract><trans-abstract xml:lang="en"><p>For the first time, reagents have been synthesized and a technique has been developed for a lanthanide immunofluorometric assay of phytohormonal steroids of 24-epicastasterone and 24-epibrassinolide. A low-molecular-weight conjugate of the brassinosteroid and an Eu3+ complexonate was synthesized by the reaction of 24-epicastasterone-6-(O-carboxymethyl) oxime N-succinimide ester with the europium salt of the diethylenetriaminepentaacetic acid N1-(aminoethyl)amide. A protein conjugate with a high specific fluorescent activity was the product of a simultaneous acylation of primary amino groups in albumin with activated esters of carboxyl derivatives of 24-epicastasterone and an Eu3+ complexonate. Using the high-molecular weight conjugate in an immunochemical system, a linear relationship was obtained between a fluorescent signal of labeled 24-epiсastasterone bound to immobilized antibodies and 24-epibrassinolide concentration in the range of 1 to 300 nM.</p></trans-abstract></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Khripach V.
