ATTO 633

ATTO 633 from ATTO-TEC has an excitation peak at 629 nm and an emission peak at 657 nm. ATTO 633 belongs to a new generation of fluorescent labels for the red spectral region. Characteristic features of the label are strong absorption, high fluorescence quantum yield, and high thermal and photo-stability. Thus ATTO 633 is highly suitable for single-molecule detection applications and high-resolution microscopy such as SIM, STED etc. Additionally the dye highly qualifies to be applied in flow cytometry (FACS), fluorescence in-situ hybridization (FISH) and many more. In common with most ATTO-labels, absorption and fluorescence are independent of pH, at least in the range of pH 2 to 11, used in typical applications. ATTO 633 is a cationic dye. After coupling to a substrate the label carries a net electrical charge of +1. The label is moderately hydrophilic. see less ATTO 633 from ATTO-TEC has an excitation peak at 629 nm and an emission peak at 657 nm.
