General description

Atto 425 is a fluorescent label with a coumarin structure. The dye is intended 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, large Stokes-shift, good photostability, and low molecular weight.
Atto 425 is moderately hydrophilic. Its fluorescence can be excited efficiently in the range 405 - 455 nm.
The azide modification is suitable for reactions with alkyne groups (Huisgen reaction - “Click Chemistry“).
