JOE azide, 5-isomer|JOE N3,5-isomer
JOE is a fluorescent dye with the emission in yellow region of the spectrum. The fluorophore matches channel of HEX dye, another chlorinated fluorescein.
JOE dye is often used in qPCR; oligo labeling can be achieved using Click chemistry. This is an azide derivative of JOE for Click chemistry, pure 5-isomer.
