Fluorescent Labeling Reagents for Proteins
Convenient kits and activated fluorescent dyes for labeling amines, sulfhydryls and other antibody or protein functional groups with FITC, fluorescein, rhodamine or one of several DyLight Fluors to create molecular probes for fluorescence imaging.
Motivated by recent advances in fluorescence detection technologies and applications, our researchers have developed improved forms of traditional dyes, entirely new fluorescent compounds and the most convenient and efficient labeling kits available.
