Live Danio in CyGEL Sustain

Resources Technical Documents DRAQ7 and Annexin V

Technical documents description.....

Live, intact cell impermeant DNA dyes are commonly combined with Annexin V (which reports membrane inversion) to give information about the progression of apoptosis.

As shown in the figure below, DRAQ7TM (top & middle series) performs in an equivalent manner to propidium iodide (PI, bottom series), to report the onset of membrane leakiness caused by increasing doses of VP-16. 

Plus, DRAQ7TM offers new possibilities as a far-red, non-enhancing DNA binding dye.  Using both log and linear displays, further discrete sub-populations can be identified.  Also, unlike PI, DRAQ7TM will permit several fluorescent parameters to be measured in parallel; 4 with blue laser excitation alone.DRAQ7 AnnV VP-16
