AF647-NHS ester (tripotassium)

AF647-NHS ester tripotassium is an analogue of Alexa Fluor 647 (AF647) (HY-D1119) . NHS ester can covalently bind to molecules with amino groups (such as proteins, antibodies, etc.) . AF647 is a bright, far-red fluorescent dye with an excitation wavelength (λex) of 635 nm (conventional fluorescence detection) /620 nm (instantaneous detection) . Storage: protect from light[1][2].
