HEX azide, 6-isomer | 1450752-91-6

Product Introduction

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.,Oligonucleotides with a HEX label can be easily generated using HEX azide and alkyne-containing oligonucleotide via azide-alkyne cycloaddition.,HEX exhibits an excitation peak at 533 nm and an emission peak at 549 in green-yellow area, and it can serve as a substitute for JOE, BODIPY™ 530/550, VIC™ because of the similar spectral characteristics.
