Complexes of a compound represented by the general formula (I): (wherein R1 through R7 independently represent hydrogen atom, halogen atom, alkyl group, aryl group, aralkyl group, sulfonate group, amino group, styryl group, nitro group, hydroxyl group, carboxyl group, cyano group, or aryl azo group; R1 through R7 may or may not be bonded to each other to form a substituted or an unsubstituted condensed ring; F1 represents a divalent organic residue; and X1<(-)> represents an anion) and the like with immunoglobulin and the like are formed.
