Atto 647N is a new generation fluorescent dye dedicated towards the red spectral region. It is a cationic dye and carries a net electrical charge of +1 post substrate coupling reaction. Streptavidin, isolated from Streptomyces avidinii, is a tetrameric protein of 4 x 13.2 kDa which binds very tightly to the small molecule biotin. The dissociation constant of the complex is extremely small (Kd ≈ 10-15 M), ranking among the strongest non-covalent interactions. Atto streptavidin conjugates are readily soluble in water.
Anwendung
Die Atto Fluoreszenzfarbstoffe wurden für die hochsensitive Anwendung bis hin zur Einzel-Molekül-Detektion (SMD) entwickelt. Sie haben eine starre Molekülstruktur, was das Auftreten einer cis-trans-Isomerisierung unterbindet. Daher besitzen diese Farbstoffe eine ausserordentlich hohe Fluoreszenzintensität mit einer geringen spektralen Verschiebung nach der Kopplung an Biomoleküle.
