Hexachlorofluorescein (HEX) is a hexachlorinated derivate of the fluorescent dye fluorescein. HEX-labeled oligonucleotides are used in PCR and the HEX channel is widely used in multiplex qPCR.
HEX carboxylic acid is a non-reactive form of HEX dye that can be used as a reference standard in experiments involving HEX dye conjugates. Besides, the carboxylic group can react with hydrazines, hydroxylamines, and amines using carbodiimides such as EDAC.
