Flow cytometric analysis of live Jurkat cells treated with Staurosporine #9953. Gated population represents DRAQ7-positive apoptotic cells.
DRAQ7® emission spectra when excited at various wavelengths.

Product Usage Information

Flow Cytometry: Prepare cells for DRAQ7 staining by resuspending cells in PBS at a concentration of no more than 5 x 105 cells/ml. For each 0.5 ml of cell suspension, dilute DRAQ7 1:100 by adding 5 μl to suspended cells, achieving a final concetration of 3 μM. Gently mix and incubate for 10 minutes on ice. Cells should be analyzed directly in the presence of DRAQ7.


DRAQ7 is provided as a 0.3 mM stock.


Store at 4°C, protected from light. Do not freeze.

Fluorescent Properties

  • Exλmax599/644 nm
  • Emλmax678/694 nm
  • DRAQ7™ may be excited by a wide range of wavelengths from 488-647 nm. Despite low absorbance at 488 nm, this excitation source allows for convenient combination with FITC and PE conjugates as well as EGFP.


DRAQ7 is a far-red fluorescent DNA dye that only stains the nuclei in dead and permeabilized cells. It can be used in combination with GFP, FITC, and PE labels.
