Beschreibung

General description

Atto 700 ist ein neues Label mit starker molekularer Absorption (1.2 x 10⁵) und Quantenausbeute (0.25), sowie ausreichend großem Stokes-Shift zwischen Anregungs- und Emissionsmaximum. Atto 700 zeichnet sich durch hohe Photo- und Thermostabilität aus. Es in Wasser außerordentlich gut löslich. Durch eine vernachlässigbare Triplett-Bildungsrate, ist es gut für Einzelmolekül-Nachweis-Anwendungen geeignet.

Application

Atto 700 belongs to a new generation of fluorescent labels. 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, high fluorescence quantum yield, excellent thermal and photo-stability, very good water solubility and very little triplet formation. Atto 700 is a zwitterionic dye with a net electrical charge of zero. The fluorescence is efficiently quenched by electron donors like guanine, tryptophan, etc.

Atto labels have rigid structures that do not show any cis-trans-isomerization. Thus these labels display exceptional intensity with minimal spectral shift on conjugation.
