ACRIDINIUM COMPOUND HAVING A PLURALITY OF LUMINESCENT GROUPSAND BINDING GROUPS, AND CONJUGATE THEREOF

摘要

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): <IMG> (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 throllgh which X binds to carbonyl carbon bonded to 9-position of the acridinium ring.
