Acridinium compounds and their conjugates exhibiting high chemiluminescence yield are provided. Such compounds may be used to enable a highly sensitive specific binding assay. The acridinium compounds are represented by formula (I):
wherein A is a linker; Z is a binding group; Y is a counter ion; R1 and R2 are independently a substituent; p and m are independently an integer of from 0 to 4; n is an integer of from 2 to 5; and X is an organic intervening moiety with a functionality of at least n, having an aryloxy group or an arylsulfonamide group through which X binds to carbonyl carbon bonded to 9-position of the acridinium ring.
本研究提供了具有高化学发光产率的吖啶鎓化合物及其共轭物。此类化合物可用于高灵敏度的特异性结合检测。吖啶鎓化合物由式(I)表示:
其中 A 是连接剂;Z 是结合基团;Y 是反离子;R1 和 R2 独立地是取代基;p 和 m 独立地是 0 至 4 的整数;n 是 2 至 5 的整数;X 是官能度至少为 n 的有机中间分子,具有芳氧基或芳磺酰胺基团,X 通过它们与键合在吖啶鎓环 9 位的羰基碳结合。
