    Fluorescent Dye
    Sulfo-Cyanine5.5 carboxylic acidCI Pigment violet 32 is a water-soluble, far-red emitting fluorophore. Due to its four sulfo groups, this dye has a negative charge at neutral pH and is very hydrophilic. As a cyanine dye, sulfo-Cyanine5.5 shows a very low dependence of fluorescence on pH and a very high extinction coefficient.

    Fluorescent Dye Others
    Sulfo-Cyanine5.5 carboxylic acid potassium is a fluorescent dye with excitation/emission wavelengths at 673/707 nm. The introduction of the sulfite group enhances the hydrophilic properties of the compound. The terminal carboxylic acid can react with primary amine groups in the presence of activators such as EDC and HATU, to form stable amide bonds.

  • HY-173308

    Fluorescent Dye Others
    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.
