AF 647 is a bright, photostable, and hydrophilic fluorophore emitting in the far-red channel (absorption max. is at 650 nm, emission max. is at 671 nm). AF 647 carboxylic acid is a water-soluble dye that can be used as a reference standard and, after activation, for synthesizing AF 647-containing biomolecules.
