Draq5 http://www.biostatus.co.uk/draq5_features.html#draq5

Main Features In vitro research purposes only Capable of stoichiometric binding to DNA inside living and fixed cells Rapid uptake into living cells (concentration range 5-10 µM x 1-5 mins; at room temp. or 37°C)

Basic features nuclear DNA live or fixed mammalian cells with minimal RNA-associated fluorescence Emission spectrum beyond 670 nm providing minimal overlap with the emissions from visible range dyes including GFP

Flowcytometry DRAQ5™ can provide cell cycle information (eg  %G0/1, %S, %G2/M) in mixed  populations identified by FITC labeling. The quality of analysis can approach that of traditional propidium iodide / ethidium bromide techniques Rapid staining of cells in seconds by simple addition of DRAQ5™ to buffer or culture medium with no need to wash prior to imaging It is not recommended for viable cell sorting since the persistence of DRAQ5™ on cellular DNA is ultimately cytotoxic
