ABSTRACT:
Novel intermediates having an indolenine nucleus which are useful in the synthesis of fluorescent sulfoindocyanine dyes are described. Dyes synthesized using such intermediates do not contain a reactive group that will covalently attach to a target molecule at an amine- or hydroxy-containing site. Rather, these intermediates are linked to an enzyme substrate or a member of a specific binding pair. Also included are tyramide-containing sulfonidocyanine dyes.
