Biostatus has introduced Draq7, a live cell impermeant far-red fluorescing DNA dye with the same spectral properties as the Draq5 reagent.
For flow cytometry applications, Draq7 rapidly labels dead, dying and apoptotic cells in cytotoxicity and viability assays, as well as fixed cell preparations.
Its far-red emission permits new combinations of dyes to be used in the understanding of apoptosis.
Draq7 is directly interchangeable with Draq5 to permit two-tube multi-colour analysis for sample quality and DNA content analysis.
For HCS and microscopy, Draq7 counter-stains fixed cell and tissue preparations.
It offers differential nucl:cyto staining for dual-compartment segmentation for translocation tracking and cell morphometrics for in-vitro toxicology.
With negligible toxicity, Draq7 can be used in RNAi knock-down and long-term, dynamic viability assays to report cytotoxicity and apoptosis.
Supplied as an aqueous, ready-to-use solution, the introductory 1ml pack is sufficient for 200 flow cytometry tests, 200 to 300 slides and 6,000 microtiterplate wells.
