What our customers are saying about DRAQ7™
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

The Science
- DRAQ7™ is a small molecule closely related to DRAQ5™. It has peak absorbances at 600nm and 646nm. It fluoresces in the far-red / near infra-red (NIR) peaking at 697nm (bound to dsDNA). On a flow cytometer it is possible to detect DRAQ7™ using blue laser (488nm) excitation.
- DRAQ7™ is detected in a far-red/NIR channel >675nm
- DRAQ7™ can be excited with a choice of laser lines
- DRAQ7™ is cross-platform compatible - flow/imaging flow cytometers and confocal/lamp-based microscopes
Flexible, multi-colour analysis:

CUSTOMER REVIEWS
What our Customers are saying about DRAQ7™:-
- "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 4-week period, reading plates every 72 hours 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!
