Comments: My colleagues and I could see a clear and bright signal even with low laser power. There was never an issue of poor dye penetration into 3D cellular aggregates, as would otherwise be observed with more common nuclear dyes, such as Hoechst . The quality of staining is usually consistent across experiments  and among different colleagues. This follows that our results were also consistent across experiments. The dye was stable after repeated uses, and the signal intensity of DRAQ7 did not decrease with repeated use. Moreover, as it is simply added to cell culture media, it fits easily into any experimental design.  I would recommend DRAQ7 to other researchers for its stability, fluorescence quality and its convenience of use. One suggestion for improvement would be to create versions in other fluorescence colors instead of just one which is presently APC.

Comments: DRAQ7 is a useful product for those wishing to visualize nuclei in the far-red.  It was as simple to use as DAPI, but may have advantages over DAPI, as you don't need to use U.V. light to excite it.

Comments: We used DRAQ7 to visualize the formation of a necrotic core in fresh isolated Islets of Langerhans, which are prone to hypoxia.  DRAQ7 was simply added to the medium to a final conc. of 1 microM. This compound appeared specific for staining the nuclei of necrotic cells only. It is easy in use, provides a fairly low background and stable regarding bleaching.

"Good results and works fine for live-cells. For fixed cells I rather use DRAQ7."

Comments: DRAQ5 stain nuclei in an easy way, I have no doubt that is one of the best, mainly in live cells, though for the specific case of my lab we rather used cell-fixed preparations, though for this case DRAQ5 works fine as well. I'd recommend DRAQ7 which is a bit better. Cons, both of them are expensive in caparison with other nuclei staining dyes.
