AF647 NHS ester is a bright, far-red fluorescent dye, used for cellular visualisation and labeling of antibodies, peptides, proteins, modified oligonucleotides, and other amine-containing molecules.
Due to the lack of significant self-quenching AF647 dye molecules can be conjugated to proteins at high molar ratios, which resulting in sensitive detection of low-abundance biomolecules potential.
AF647 NHS ester dye possesses high water-solubility, high fluorescence quantum yield, it is pH-insensitive over a wide molar range. Widely applied for imaging and flow cytometry.
