Comments: DRAQ5 was used to visualize nuclei in live HeLa cells using confocal fluorescence microscope LSM 510. This product is very stable and convenient to use. The protocol involving dilution and staining is very simple and easy to follow. The dye is not toxic to HeLa cells and bio-safe. The dye did not interfered with subsequent downstream biochemical analysis e.g. western blot and protein band detection by LI-COR.  DRAQ5 uses far red wavelength, it does not involve the risks associated with UV light as associated with some other nuclear staining dyes in market. Also it was advantageous to us since nuclei visualization was the most essential part of our experiments and DRAQ5 imaging was compatible with our LSM 510.

Comments: After assay optimization, this product worked quite well for imaging host cells by microscopy during bacterial infection. The product has a long shelf life, provided consistent results, and was not that expensive.
