Comments:                 We used CyGel for imaging a K562 cell line to verify that our fluorophore-tagged biosensor is internalized by the cells. The product was very easy to use and worked according to the manufacturer’s description. There was no problem with CyGel interfering with our fluorescent signal using a standard fluorescent microscope for cell imaging. We think it was a very reasonable price for the ease of use and results we obtained. While we did not require follow up service, it was there for our assistance as needed.

Comments: DRAQ7 was used to measure cell death in complement-dependent-cytotoxicity experiment.  

Our project was to determine the ability of anti-Tn antibody to mediate death of Tn expressing in association with complement. Briefly, Tn expressing cells were incubated with anti-Tn antibody, in the presence of complement and DRAQ7 as a viability marker. Cell were incubated in Incucyte System (www.essenbioscience.com/en/products/incucyte?gclid=CObfsKOZjM8CFWMW0wodVw0JSQ) and the appearance of red fluorescence (staining of dead cells by DRAQ7) was monitored every 30 minutes.  We were able to measure cell death over time by the use of DRAQ7. Fluorescence emission signal was high, and the results obtained were reproducible.

Among all viability dye we have tested, it was the only one that emits strong signal after several hours of incubation.

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.
