1,10-phenanthroline-2,9-dicarboxylic acid and novel derivatives thereof such as 4,7-diphenyl-1,10-phenanthroline-2,9-dicarboxylic acid and 4,5,9,14-tetraaza-(1,2,3,4)-dibenzanthracene-3,5-dicarboxylic acid can be coupled to proteins through coupling groups to form conjugates which form highly fluorescent chelates in the presence of lanthanide salts. Derivatives of the above acids reactive toward proteins can be readily manufactured by relatively simple synthetic routes, and are useful in fluorescent immunoassay.
1,10-菲罗啉-2,9-二羧酸及其新型衍生物,如 4,7-二苯基-1,10-菲罗啉-2,9-二羧酸和 4,5,9,14-四氮杂-(1,2,3,4)-二苯并蒽-3,5-二羧酸,可通过偶联基团与蛋白质偶联,形成轭合物,在镧系元素盐存在下形成高荧光螯合物。 上述酸类对蛋白质有反应性的衍生物可通过相对简单的合成路线方便地制造,可用于荧光免疫测定。
