Andy Fluor 680 free acid

Andy Fluor™ 680 is a bright, near-IR dye that is spectrally similar to the Cy5.5 dye. Andy Fluor™ 680 is water-soluable, highly fluorescent and pH-insensitive from pH 4 to pH 10. Andy Fluor™ 680 can be used as a replacement for Alexa Fluor 680, DyLight 680, Cy5.5, IR Dye 680.

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.
