Superior to propidium iodide.
Rating: 5.0

  • Application Area:cell viability, FACS

"DRAQ7, a cell impermeant DNA stain, is great to assess cell viability using FACS: low autofluorescence in the infrared, ease to combine it with other fluorophores in the visible range. Much better than propidium iodide on the last account."

Great for imaging cell death as well as FACS
Rating: 4.0

  • Application Area:Small molecule cell death screens

"Draq7 offers a great means in which to image cell death in real time. Although the product is commonly used as a FACS marker for cell death, I have found great utility as a way to real time mark cell death using Incucyte. Con is price is slightly higher than competitor products used previously, but Draq7 is still my go to marker for cell death"

  • Application Area:High Content Screening

"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! "

"We used to stain nuclei DRAQ7 cardiac tissue of rats that developed cardiac hypertrophy embedded in paraffin. The reagent was quite stable, not gender line, besides having a very long life."

  • Application Area:Viability dye in whole blood flow cytometry

"We have used DRAQ7 as a convenient viability dye in whole blood Lyse-no Wash flow cytometry protocols, included in a 8-color panel. The staining we got was excellent and no major compensation issues arrived. We will definitively keep using this dye in further projects. "

"The greatest characteristic of DRAQ7 is Ease of Use. Short incubation time (~10 min) and excitation by near-infrared wavelength allow us to sort and eliminate dead cells in flow cytometric analysis easier. This dye also has good performance considering its low price."

"This product is user-friendly and does not require much effort to use. It gives good results and is clear. It can be used for a time acceptable. In addition, the company's service was superior in terms of response and availability. I am very pleased and I know I will contact the company again when I need to. "

  • Application Area:Live cell screening

"Draq7 is a great dye for labelling cells and is very easy to use. Using this dye we have been able to do live cell screening of cells, as it is non-toxic to cells. However, overall the cost is a bit expensive for screening."

Review date: 31 Dec 2012 | DRAQ7
DRAQ7 fluoresces in the far-red – with the same spectral properties that have made DRAQ5™ a reagent of choice in HCS.

DRAQ7™ only labels membrane-compromised dead, dying and apoptotic cells and gives clear discrimination between these and healthy cells in high content cytotoxicity and viability assays and in flow cytometry.

The far-red emission, longer wavelength than TOTO-3, permits better combination with other fluorescent probes. It is spectrally compatible with the commonly used orange/red mitochondrial health probes, and UV-excited vital dyes.

DRAQ7 can be used in RNAi knock-down and long-term, dynamic viability assays to report in vitro cytotoxicity and apoptosis.

Also, DRAQ7 efficiently counterstains fixed cell and tissue preparations. It offers the same differential nucl:cyto staining for dual compartment segmentation in translocation tracking and cell morphometrics for in vitro toxicology, that has made DRAQ5™ a favourite of HCS assay developers.
 
DRAQ7 is supplied as a convenient aqueous, ready-to-use solution. The 1 ml pack size (GBP 140.00 / ca. USD 220.00) is sufficient for at least 200 flow cytometry tests, 300-600 slides and up to 10,000 1536-MTP wells.
