Comments:                 For many years, my core facility users in general and I, personally, have been using several BioStatus products, mainly DRAQ5 and DRAQ7. I have always found them effective and extremely easy to use. DRAQ7 has shown for many years to be a fantastic option for the detection and exclusion of dead cells. Quite recently, we have tested and used DRAQ7 DROP & GO for the detection and exclusion of dead cells from a very heterogeneous sample for isolating photoreceptors from adult zebrafish retinae for downstream RT-PCR. It was as easy as described in the name of the product "drop and go". Dead cells were clearly differentiated from the alive ones as can be easily observed in our recently published paper Glaviano et al. "A method for isolation of cone photoreceptors from adult zebrafish retinae" BMC Neuroscience (2016) 17: 71 (DOI 10.1186/s12868-016-0307-2)

"Best nucleic acid stain"

PRODUCT:                  DRAQ5

Application Area:        Staining nuclei in 3D tissue constructs (tissue engineering application)

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

Value for Money:        ⭐⭐⭐⭐⭐
Average rating:           5.0

Comments: Product (DRAQ5) nucleic acid stain works exceptionally well, and keeps common microscope filter channels open since it's a far red stain. Little to no background, easy to use and store. Penetrates deep into thick tissues so you don't observe staining concentration gradients as with other nuclear stains. Perfect for use when imaging 3D tissue constructs with confocal - but also works well for 2D monolayer applications where UV light isn't an option (ex: PMMA microfluidic devices which block UV).

"Very useful for in vivo staining, easy to handle, high-quality"

PRODUCT:                  DRAQ5

Application Area:        Staining living mouse embryonic fibroblast nuclei

Ease of Use:              ⭐⭐⭐⭐⭐

Comments: If you are looking for a dye for in vivo staining, DRAQ5 is the best. Even with very little amount of a stock of the product, like 1ul, you can observe bright nuclei immediately. Staining genomic DNA specifically you could capture where DNAs are distributed in nuclei. After decorating your nuclei with it, cells are still happy living healthy. I will keep using the product for my future projects.
