Cat. No.: HY-D2160
AF 647 carboxylic acid is a derivative of the far-infrared dye AF 647. AF 647 is often used as a replacement for Cy5 dye, with an excitation wavelength (λex) of 635 nm (conventional fluorescence detection)/620 nm (instantaneous detection). The maximum excitation wavelength is 647 nm and the maximum emission wavelength is 671 nm. AF 647 carboxylic acid has a carboxylic acid group and can be coupled to biomolecules with amino groups to achieve dye labeling .

QSY-21 is a fluorescence quencher. QSY-21 possesses broad absorption in far red and NIR range, and can quench fluorescence of dyes that emit in this region. This is a carboxylic acid derivative. QSY-21 has intense absorption maximum at 661 nm, making it useful as an acceptor in fluorescence resonance energy transfer (FRET) applications. It is a common quencher for Cyanine5, Cyanine5.5, AF 647, or other spectrally similar fluorescent dyes.
