Using the fluorescent group-containig 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-Y3-N=C=N-Y2-W-Y1-[A]n-F (I)
wherein F represents a fluorescent group;
A represents a moiety selected from the group consisting of -CH2-, -NHCO-, -CONH-, -O-, -S-, -NR- wherein R is an alkyl group, -COO-, -OCO-, -NHSO2-, and - SO2NH-;
n is 0 or 1;
W represents a direct bond or a quaternary ammonium group;
Y1, Y2 and Y3 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-Y1-[A]n-F.
