6-HEX SE

The activated NHS-ester of HEX (Hexachlorofluorescein) dye is a pure 6-isomer, designed for amine-reactive labeling of proteins, peptides, amino-modified oligonucleotides, and other amine-containing molecules. HEX is a hexachlorinated derivative of fluorescein, featuring an excitation peak at 533 nm and an emission peak at 549 nm in the green-yellow spectrum. Due to its similar spectral properties, HEX can serve as an alternative to dyes such as JOE, BODIPY(TM) 530/550, and VIC(TM). HEX NHS ester is widely utilized in applications such as nucleic acid sequencing, PCR/qPCR, and other related research fields, making it a valuable tool for fluorescence-based studies.
