General description

Atto MB2 NHS ester is a derivative of the well-known redox dye Methylene Blue. The dye can be reversibly reduced to the colorless leuko form. Upon oxidation (e.g. with oxygen) the dye recovers, and the absorption is fully restored.
The dye is suitable for labeling of DNA, RNA, proteins etc. In common with most Atto-labels the dye shows a high extinction coefficient.
Atto MB2 NHS ester is moderately hydrophilic.
