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.

Application Area: Live cell screening DRAQ7™ Novel Cell-Impermeant DNA Dye
"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."
