Comments: We easily got good results. The product was easy to use, although for us in countries with devalued currency it is quite expensive. This is however the same for any imported reagent, so I would say the value for money was OK.

Comments: This has enabled us to do experiments that were not otherwise possible before. Not only is it a much cleaner signal than other viability dyes, but the fact that it is non-toxic has enabled us to do time courses with the same samples. We have performed 3D spheroid experiments over a 4week period, reading plates every 72hours with zero toxicity! It therefore saves us large amounts of money that would have been spent on ending experiments at each time point using toxic dyes. Highly Recommended!

Value for Money:        ⭐⭐⭐

 Average rating:          3.7

Comments: Very easy to use (one step direct staining), did not work well with cat  blastocyst though - we have no explanation why.  Very stable (at least 6 weeks in refrigerator after mounting on slides). It took some time to order to Sweden (through middle steps, not sure if we used the right channels). Equivalent to Hoechst or DAPI but more expensive. Excellent for our confocal that does not have a blue laser.

Comments: DRAQ 5 is an excellent product that is easy to use. I would recommend it to anyone wishing to stain DNA in live or fixed cells. One major benefit over other nuclear stains is that excess dye does not need to be washed out as is the case with many other DNA stains.

We did not have any discussion with the company after purchase simply because none was necessary.

Value for Money:        ⭐⭐

Average rating:           3.7

Comments: DRAQ5 is our most established nuclear stain for cell based assays. It also stains the cytoplasm to some degree which is useful for cytoplasm detection. It's emission in the far red is useful as it does not cause cross signals on lower wavelength-excited channels (while Dapi or Hoechst do)! It is quite expensive though! After sales care not required.

Comments: DRAQ5 is incredibly easy to use. Just dilute and add to cells immediately before acquiring days. Dye incorporates quickly into both live and fixed cells. It also gives a nice bright stain of the nucleus that has crisp edges. Post-sales, the company was always readily available for any questions or to help with designing experiments with any of their other products. DRAQ5 is excitement stable, even with left diluted at room temperature and very little dye is needed to stain cells.
