Andy Fluor 546 free acid


Andy Fluor™ 546 is a bright, orange-red fluorescent dye spectrally similar to Cy3 dye. However, compared to Cy3, Andy Fluor™ 546 is much brighter and more photostable. Andy Fluor™ 546 can be used as a replacement for Cy3, TAMRA.

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.
