DRAQ7: a unique real-time cell health monitor

DRAQ7™ enables real-time toxicity and viability assays

• DRAQ7™ is non-toxic to cells over several days exposure
• DRAQ7™ does not alter dose-response profiles for anti-cancer agents
• DRAQ7™ gives a sensitive real-time readout for cell death induced by hypoxia, starvation, drug treatment .. 
• DRAQ7™ has full spectral compatibility with Hoechst 33342, FITC/GFP and the orange/red MMP probes

DRAQ7 Improves SP Analysis

DRAQ7™ permits a new kinetic understanding of SP analysis.  

• Membrane-impermeant DRAQ7™ allows removal of interfering Hoechst signals coming from dead and damaged cells. 
• DRAQ7™ is non-toxic, does not passively enter intact cells during the extended exposure times required and also allows sorting of the viable SP sub-populations. 
• DRAQ7™ has no UV-excitation, avoiding PI's red emission overlap. 
• Far-red DRAQ7™ permits multi-colour phenotypic SP analysis.
