Beschreibung

Application

Atto 647 belongs to a new generation of fluorescent labels for the red spectral region with high molecular absorption (120.000) and quantum yield (0.20) as well as sufficient stoke′s shift (excitation maximum 645 nm, emission maximum 669 nm). Atto 647 is characterized by a high photostability. The dye is designed for application in the area of life science, e.g. labeling of DNA, RNA or proteins. Atto The dye is very stable under physiological pH-values and in buffers up to pH 8.5. However, it slowly degrades at higher pH. Atto 647 maleimide shows excellent solubility in polar solvents like DMF, DMSO or acetonitrile. After coupling to a substrate the dye moiety is electrically neutral.
