ATTO 655 on AmC6; 5' Modification
The 5-ATTO 655 modification incorporates an ATTO™ 655 dye (ATTO-TEC GmbH) at the 5' terminus of an oligonucleotide. ATTO 655 modifications exhibit exceptionally high ozone stability, high thermal and photo-stability. With good water stability, strong absorption and high fluorescence quantum yield, ATTO 655 can be used in a wide array of applications, including single molecule detection, high-resolution microscopy, flow cytometry (FACS), and fluorescence in-situ hybridization (FISH). ATTO 655 is an alternative for Alexa Fluor® 660; particularly where enhanced photostability is desired. ATTO 655 fluoresces in the red region of the visible spectrum and its fluorescence can be effectively quenched by BHQ®-3 dye.
