Description

Application

Atto 647N belongs to a new generation of fluorescent labels for the red spectral region. 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, excellent fluorescence quantum yield, high photostability, excellent ozone resistance, good solubility, and very little triplet formation. Atto 647N is a cationic dye. The active ester of Atto 647N fluorescence dye reacts with amino groups under mild conditions. After coupling to a substrate the dye carries a net electrical charge of +1. In common with most Atto-labels, absorption and fluorescence are independent of pH in the range of 2 to 11, used in typical applications. As supplied Atto 647N consists of a mixture of two isomers with practically identical absorption and fluorescence properties.

General description

Atto 647N is a superior red-emitting fluorescence dye with a strong absorption, excellent fluorescence quantum yield (65%), high photostability, excellent ozone resistance, good solubility, and very little triplet formation.
