Average rating:           3.7

Comments: DRAQ5 is our most established nuclear stain for cell based assays. It also stains the cytoplasm to some degree which is useful for cytoplasm detection. It's emission in the far red is useful as it does not cause cross signals on lower wavelength-excited channels (while Dapi or Hoechst do)! It is quite expensive though! After sales care not required.

Comments: DRAQ5 is incredibly easy to use. Just dilute and add to cells immediately before acquiring days. Dye incorporates quickly into both live and fixed cells. It also gives a nice bright stain of the nucleus that has crisp edges. Post-sales, the company was always readily available for any questions or to help with designing experiments with any of their other products. DRAQ5 is excitement stable, even with left diluted at room temperature and very little dye is needed to stain cells.

Comments: Overall DRAQ5 is an excellent product with simple and easy to use instructions.  The dye has very good sensitivity and specificity and can be easily plugged into any protocol with minimal change.  DRAQ5 has cut down on protocol time and the high concentration of the stock solution allows one to conduct multiple studies with one vial of solution; thus dramatically reducing costs and time compared to similar nuclear dyes.

Comments: We need to counterstain for DNA in most of our experiments using human cells. DRAQ5 is rapid, simple and very efficient and, very importantly, requires a far-red excitation, much more common and less toxic for live cells than UV lasers (required for DAPI/Hoechst staining).

Value for Money:        ⭐⭐⭐⭐⭐

Average rating:           5.0

Comments: We have used DRAQ5 for Amnis ImageStream analysis for several years now and it has a nice consistently bright staining. We found this dye to be more reliable and less problematic (bleeding into subsequent samples, contaminating tubes, compensation issues) than various other dyes such as Dapi and hoechst dyes. We add 2-3ul of a 1:1000 dilution to our cells (1-2x10^6)/100ul just before acquisition. Officially our vial has expired (for at least a year), but we have seen no reduction in signal. We have used DRAQ5 for traditional flow-cytometry as well, to either eliminate or select cell-doublets or 2-cell conjugates. For flow we use a 10-fold higher concentration than for imaging, which makes it less cost-effective than some other live dyes in this setting.

Comments: This product is very useful for us in intracellular staining of receptors for localization. It is an easy to use nuclear counter stain because of its advantageous spectral properties (it does not cover at least two or three out of the available visible range optical channels in confocal microscopy, like propidium iodide). Sometimes we can also utilize its unique property that it does not need cell permeabilization that other nucleic acid stains require.

• Ease of Use:              ⭐⭐⭐⭐

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

Comments:                CyGel Sustain was our miracle solution to perform the extremely technically challenging intraocular injections in zebrafish larvae at 2 days post fertilization, in a 100% accurate and reproducible way. Thanks to CyGel Sustain we could immobilise these larvae (no more than 2 mm long) and carry out the intraocular injections into their eyes (no more than 50 microns diameter) under the dissecting microscope. After injection, CyGel was reverted to liquid and larvae recovered with no damage (Reference(s): Alvarez, Y., et al. PLoS One 4.11 (2009): e7867.) We have used CyGel Sustain since then for different protocols where safe and reversible immobilization of the small larvae is needed with excellent results. Biostatus outstanding support and contribution for the refinement of our protocols and overcome of technical difficulties, is not easy to find among the post-sale service of other companies.
