Uses
Cyanine3 amine hydrochloride, an analog of Cyanine3 amine, is a potent green fluorescent dye. Cyanine3 amine hydrochloride has the primary amine group and is covalently coupled with reactive groups such as NHS esters, carboxy groups (after carbodiimide activation), and epoxides. (λex=555 nm, λem=570 nm)[1].
