HEX NHS ester, 6-isomer (LP2B220)

Activated NHS-ester of HEX (Hexachlorofluorescein) dye, a pure 6-isomer. This NHS ester is an amine-reactive dye for labeling of amine groups in proteins, peptides, amino-modified oligos, and other target molecules. HEX is a hexachlorinated derivate of the fluorescent dye fluorescein. HEX exhibits an excitation peak at 533 nm and an emission peak at 549 in the green-yellow area. It can serve as a substitute for JOE, BDP™ 530/550, VIC™ because of their similar spectral characteristics. HEX NHS ester is widely used in nucleic acid sequencing, PCR/qPCR, and related research.
