AF 647 NHS ester is a bright, far-red fluorescent dye, used for cellular visualization and labeling of antibodies, peptides, proteins, modified oligonucleotides, and other amine-containing molecules.

Due to the lack of significant self-quenching AF 647 dye molecules can be conjugated to proteins at high molar ratios, resulting in the sensitive detection of low-abundance biomolecules potential.

AF 647 NHS ester dye possesses high water-solubility and high fluorescence quantum yield; it is pH-insensitive over a wide molar range. Widely applied for imaging and flow cytometry.
