MedKoo CAT#: 558813


Description: Rhodamine 6G (R6G) is a xanthene dye of rhodamine series. Compared to fluorescein, its emission is shifted to red. It is also much more photostable. The fluorophore has a high quantum yield. This R6G product contains a terminal alkyne moiety for the conjugation with azides in the presence of copper (I) catalyst.
