The 5-ATTO 390 modification incorporates an ATTO™ 390 dye (ATTO-TEC GmbH) at the 5' terminus of an oligonucleotide. ATTO 390 modifications exhibit a large Stokes-shift, high thermal and photo-stability, and low molecular weight. With strong absorption and high fluorescence quantum yield, ATTO 390 can be used in a wide array of applications. ATTO 390 fluoresces in the blue region of the visible spectrum and its fluorescence can be effectively quenched by BHQ®-1 dye.
