Abstract

Novel vinylsulfone Cyanine Dyes (em. 550-850 nm) were designed and synthesized for fluorescent labeling of biomolecules via 1,2-addition reaction in aqueous conditions. Due to the virtue of chemical structures of both fluorophore and reactive group, these dyes could be significantly stable and reactive in various aqueous/organic conditions. A wide variety of pH, temperature, buffer concentration, and protein were tested for the optimal labeling condition.
