Andy Fluor 647 free acid


Andy Fluor™ 647 is a bright, far-red fluorescent dye with excitation ideally suited to the 633 nm laser line. Andy Fluor™ 635 is water-soluable, highly fluorescent and pH-insensitive from pH 4 to pH 10. Andy Fluor™ 647 can be used as a replacement for DyLight 649, Cy5.

The NHS ester (or succinimidyl ester) is the most popular amine reactive group for labeling with the primary amines (R-NH2) of proteins, amine-modified oligonucleotides, and other amine-containing molecules. The resulting Andy Fluor™ conjugate will exhibit brighter fluorescence and greater photostability than the conjugates of other spectrally similar fluorophores.
