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. The only reason I gave 4 starts for the After Sales Care is because I had no direct interaction with them, but I think our lab tech found the initial instructions with the package confusing. Overall, it is a great product for a specific assay.

Comments: DRAQ7, a cell impermeant DNA stain, is great to assess cell viability using FACS: low autofluorescence in the infrared, ease to combine it with other fluorophores in the visible range. Much better than propidium iodide on the last account.

Comments: DRAQ5 works well as a nuclear label and allows us to use a different spectral range for configuring our multi-label assays.  It appears (not 100% sure why) that DRAQ5 has less particulate and non-specific labelling in our microvascular endothelial cells than Hoechst.

It has a good stability after storage.

Draq5 is a stable fluorescent Live-Cell Permeant DNA Dye which allow us to normalize the fluorescence signal between wells in an in Cell Western Blotting (Odyssey). We followed protein expression (Fluorescence 1) in bone marrow derived macrophages after different cell culture conditions and Draq5 signals (Fluorescence 2) provided us a good linearity for normalization of protein signals well-to-well (ration Florescence1/Fluorescence2).

Average rating:           5.0

Comments:                 We have used CyGEL to immobilize Drosophila pupae for live imaging using a confocal microscope. Embedding of samples in glass bottom dishes is carried out using a fluorescence stereomicroscope. We find CyGEL more convenient than LMP agarose because it saves the hassle to melt agarose and have a heating block or water bath nearby to keep agarose liquefied. The only utensil required is a small container with ice to keep CyGEL in its liquid form. Toxicity was not an issue since samples survived 3D time-lapse imaging for five days (see http://rsos.royalsocietypublishing.org/content/3/2/150517). Overall, we are very satisfied with this product.

Comments: We achieved reproducible results in a high quality. DRAQ5 was really easy to use. We needed small amounts (1:1000) to make nuclei visible during immunofluorescence analysis. An Incubation for 10 minutes with 1:1000 DRAQ5 in Medium was enough to stain nuclei and it wasn’t indispensable to change/discard medium for microscopy.

Comments: DRAQ-5 is really easy to use for visualization of nuclei during immunofluorescence analysis. For simple samples (cells in monolayers) it is great. However, for samples with many layers it does not penetrate all layers equally. For that reason, such "difficult" samples are not reproductive in 100%.

Comments: This has enabled us to do experiments that were not otherwise possible before. Not only is it a much cleaner signal than other viability dyes, but the fact that it is non-toxic has enabled us to do time courses with the same samples. We have performed 3D spheroid experiments over a 4week period, reading plates every 72hours with zero toxicity! It therefore saves us large amounts of money that would have been spent on ending experiments at each time point using toxic dyes. Highly Recommended!
