Fluorescent group-containing carbodiimide compound

Abstract

Using the fluorescent group-containing carbodiimide compound represented-by the following formula (I) as the label and the like in the nucleic acid detection method, immunoassay, or chemiluminescence assay, labeling can be made efficiently for a short time, a nucleic acid derived from nature can be labelled, and highly sensitive assay is enabled. B--Y.sup.3 --N.dbd.C.dbd.N--Y.sup.2 --W--Y.sup.1 --›A!.sub.n --F(I) wherein F represents a fluorescent group; A represents a moiety selected from the group consisting of --CH.sub.2 --, --NHCO--, --CONH--, --O--, --S--, --NR-- wherein R is an alkyl group, --COO--, --OCO--, --NHSO.sub.2 --, and --SO.sub.2 NH--; n is 0 or 1; W represents a direct bond or a quaternary ammonium group; Y.sup.1, Y.sup.2 and Y.sup.3 each represents an alkylene group which may have a functional group in its main chain; and B represents H or a monovalent organic group which may be the same as or different from that represented by --W--Y.sup.1 --›A!.sub.n --F.
