Staining solution reagent DRAQ7™

dyefor flow cytometry

DRAQ7™ is a new far-red fluorescent DNA dye that ONLY stains the nuclei in DEAD and permeabilized cells. DRAQ7™ has many applications in imaging, cytometry and screening and is highly compatible with existing protocols across a wide range of instrumentation platforms. DRAQ7™ is available in two concentrations: 0.3mM and 1mM. The 0.3mM Packs come in two sizes; 250μl and 1ml. The 1mM Pack comes in one size - 1ml - and is meant for higher volume applications. Please get in touch if you would like to order bulk volumes of DRAQ7™. Multi-wavelength imaging with UV / vis fluorochromes: NO fluorescence enhancement upon DNA binding low photobleaching effect compatible with optics of flow, laser scanning cytometers and confocal and lamp-based fluorescence microscopes Why DRAQ7™? DRAQ7™ is an ideal far-red DNA counterstain for IF/IHC, high content screening and cell-based assays. DRAQ7™ has many applications and is highly compatible with existing protocols across a wide range of instrumentation platforms. Key benefits include:- does NOT enter intact, live cells it is excited by blue through red lasers DRAQ7™ is NON-TOXIC in long-term culture an ideal replacement for propidium iodide (and 7-AAD) having far better spectral properties: no UV excitation and no emission overlap with PE and homologues allows a new design of combination analysis for cell health and status viability/integrity can be directly interchanged with DRAQ5™ (DNA content) rapid staining of dsDNA/nuclei of DEAD or permeabilised cells combination with live cell dyes for dead/live discrimination easy to use - no wash, no RNase needed
