A chemiluminescent assay method, compositions, kits and chemiluminescent acridan compounds are described which use a two-step chemiluminescent reaction process. The reaction involves an acridan compound, preferably a derivative of an N-alkylacridan-9-carboxylic acid, which undergoes a reaction with a peroxide compound, a peroxidase enzyme and an enhancer under conditions of time, temperature and pH which permit the accumulation of an intermediate compound, which is subsequently induced to produce a burst of light by raising the pH. The result is generation of very high intensity light from the reaction. The peroxidase enzyme is present alone or linked to a member of a specific binding pair in an immunoassay, DNA probe assay or other assay where the hydrolytic enzyme is bound to a reporter molecule. The method is particularly amenable to automated assays because of the separation of the incubation and light generating steps.
描述了一种化学发光测定方法、组分、试剂盒和使用两步化学发光反应过程的化学发光吖啶化合物。该反应涉及一种吖啶化合物,最好是N-烷基吖啶-9-羧酸的衍生物,它在过氧化物化合物、过氧化物酶和增效剂的作用下发生反应,在时间、温度和pH条件下积累中间产物,随后通过提高pH诱导产生一阵光。结果是从反应中产生非常高强度的光。过氧化物酶单独存在或与特定结合对的成员连接在一起,在免疫测定、DNA探针测定或其他测定中,水解酶与报告分子结合。该方法特别适用于自动化测定,因为孵育和产生光的步骤分开进行。
