Atto 610 belongs to a new generation of fluorescent labels invented by ATTO-TEC. The dye is designed for application in the area of life science, e.g. labeling of DNA, RNA or proteins. Characteristic features of the label are strong absorption, high fluorescence quantum yield, high photostability, good water solubility, and very little triplet formation. Atto 610 is a pH sensitive product. While practically stable up to pH 8.5, it slowly degrades at higher pH. Atto 610 has been coupled to streptavidin to enable all kinds of assays based on the specific affinity of biotin to streptavidin. Streptavidin conjugates are used as secondary detection reagents in histochemical applications, flow cytometry, microarrays, blot analysis and immunoassays.
