Fluorescent Labeling Dyes

Fluorescent labeling dyes are commonly used in protein binding or localization studies. These dyes can be incorporated at several positions of peptide chains. Frequently, they are incorporated at the N-terminus or at Cys/Lys side chains. Fluorescent dyes allow scientists to detect a specific stimulus or particular components in complex bio-assemblies with high sensitivity and selectivity.

Fluorescent dyes are usually used to modify amino groups, sulfhydryl groups, carboxyl groups and other biological molecules. Among these reactive dyes, amine-reactive fluorescent dyes are most often used to prepare bioconjugates for immunochemistry, fluorescence in situ hybridization (FISH), cell tracing, receptor labeling and fluorescent analog cytochemistry. Thiol-reactive fluorescent dyes are usually used to probe biological structures, functions and monitor the changes in protein conformation. Carbonyl-reactive fluorescent dyes are widely used for modifications of carbohydrates, glycoproteins and nucleic acids and ketones into the water-soluble biopolymers.
