Good lipid stain
Short-term membrane staining
DRAQ9 was a gift from BioStatus. We used it to determine if the vacuoles that we were observing in mammalian cells under hypotonic stress are surrounded by a lipid membrane. DiI that we tried before failed to stain the vacuoles, but with DRAQ9 the result was unequivocally positive: a bright staining was easily detectable under a confocal microscope. The presence of lipid was confirmed with Nile Red. We published the image in Fig. 5 of https://www.nature.com/articles/s41598-024-79815-z.pdf

DRAQ9™ is a new member of the DRAQ™ family of probes, specficially designed for the following applications:
- Long-term cell tracking: DRAQ9 is non-toxic and nuclear "dark"
- Cell painting / cell mosaic: DRAQ9 labels membranous structures (e.g. Golgi body) in live- or fixed-end point assays to reveal phenotypic changes
