DRAQ7 1 mL

DRAQ7™ is a far-red emitting, anthraquinone compound that stains nuclei in dead and permeablized cells. It is non-permeant to live cells and thus can be used for differentiating live and dead cells. It is optimally excited at 633 nm, and can be detected using 695LP, 715LP, and 780LP filters. DRAQ7™ can also be used in cell imaging as it does not get excited by UV or Violet lasers and is sub-optimally excited by the 488 nm laser. It can be combined with FITC, PE, and other UV or violet excitable dyes for multi-color analysis. DRAQ7™ is non-toxic and thus can be used for siRNA studies and other dynamic viablity assays.;
