Comments: The product worked well. Our main problem with these stains is that they cannot be used in any microscope, e.g. Draq5 can be used in a confocal laser microscope, but cannot be used in another, simpler microscope, so we have to purchase different stains for different microscopes. In addition, DraQ5 is more expensive than other similar stains.

Manufacturer's response: Thank you for your review of DRAQ5. You are right that few epifluorescence microscopes have far-red detection capabilities. You may wish to explore the use of CyTRAK Orange which is excited optimally at 510 nm (488 ex. compatible) and with peak emission at 615 nm (“rhodamine" channel). We do appreciate your concern about pricing.. sadly we have no legal control over end-user pricing by our channel partners. You might, however, consider purchasing direct from BioStatus for the keenest price, fastest service and our expert technical support.

"An easy-to-use DNA dye suitable for tissue clearing of mouse brain samples"

PRODUCT:                  DRAQ5

Application Area:        Fluorescence microscopy counterstain for tissue clearing samples

Ease of Use:              ⭐⭐⭐⭐⭐
After Sales Service:    ⭐⭐⭐⭐⭐

Value for Money:        ⭐⭐⭐⭐
Average rating:           4.7

Comments: The DraQ5 fluorescent probe is supplied as a water-soluble concentrated solution (0.5mM or 5mM) that can be diluted depending on the desired application. Given its high affinity for double-stranded DNA, DraQ5 can be used as a nuclear counterstain in immunohistochemistry studies upon short incubation periods of time, as an alternative to blue-fluorescent DNA-binding probes. However, the broad excitation and emission peaks must be taken into account if a combination with other fluorophores is desired. In our experience, it is also compatible with aqueous-based tissue clearing techniques, rendering a uniform labelling across entire mouse brain hemispheres (55-days-old) that could be imaged by light-sheet fluorescence microscopy. To achieve this, a simple incubation at 37⁰C/60rpm for 12h with a DraQ5 diluted solution (2.5uM) and a 12-hour washing step at 4⁰C to remove excess were incorporated in the tissue clearing procedure.

Comments:                 Without Cygel it would be almost impossible to obtain high-quality microscopy of motile forms of Leishmania parasites. The product is easy to use and gives a reproducible performance. I've used it to image Leishmania promastigotes that were modified to contain fluorescent proteins, in order to gain information on protein function. Cellular morphology remained unchanged by the embedding process and protein localization was not affected. Can highly recommend Cygel.

Name: Zi Wang

.........................................

Manufacturer's response: Dear Zi, It would be helpful to understand what the issue was in more detail. If staining is not stable over time that can be the case in live cells, where after several hours a re-distribution can occur in some cell types, mostly towards lipophilic structures in the cytoplasm (Martin, 2005). If the staining is not stable in fixed cells then this may be due to washing post-staining, too low concentration, or not removing surfactants used in prior cell permeabilisation procedures.

"Excellent nuclear stain. Easy to use. Works well with other common stains"

Comments: DRAQ5 is simple to use since a washing step is not required. It provides a strong signal and good visualization of cell nuclei when used in confocal laser scanning microscopy (CLSM). Its red fluorescent spectrum makes it a suitable stain to work with in conjunction with other common blue and green stains as signal overlap can be avoided.

Average rating:          2.7

Comments: DRAQ5 is generally easy to use. The spectra are in long wavelength that can be paired with many other fluorophores and thus our choice of nucleus dye for confocal imaging. However, the performance is not very stable, sometime it can be very dim and unspecific staining outside the nucleus can be seen. The product (from Thermo Fisher) is very expensive. It will be good if the price can be more reasonable.

.........................................

Manufacturer's response: Dear Yuning, thank you for detailed review of DRAQ5. Without seeing examples of the issues you raise it is difficult to give further technical advice. The occasional cytoplasmic staining you describe is often a symptom of understaining or washout due to residual surfactant left over from a prior washing step. Regarding cost, there are a number of other carefully selected suppliers you can choose from and we can advise on the most competitive of these or alternatively order direct from us, the source!

Comments: DRAQ5 is very easy to use. You resuspend cells in PBS, stain cells in dark for 1-3 minutes, then you can image cells directly (no rinsing is needed). The product is kind of expensive, but it is worth it. The dye can be excited by either 488 or 639 nm laser, but emits in far red, so it won't interfere with GFP.

The product code is DR05500 and, having reviewed your protocol, would perhaps allow you to skip the pre-dilution step entirely e.g. 4 µl into a final volume of 100 µl would give a final concentration of 20 µM. Perhaps this might assist you better?
