Description_x000D_ Application_x000D_ Fluorescence microscopy, click chemistry, fluorescence spectroscopy._x000D_ Features and Benefits_x000D_ LightOx58 is a fluorescent molecule that exhibits solvatochromatic fluorescence emission when excited with UV-A and violet (405 nm) light sources. In the free, unconjugated form LightOx58 can be used as an intracellular lipid droplet stain, and when photoactivated in a cellular environment, causes cell death through the release of reactive oxygen species (ROS). The N-propargyl group can also be utilized for ′click′ chemistry attachment to an azide-substituted molecule. In a non-polar cellular environment, peak emission wavelength is observed at 475 nm. Stock solutions are typically prepared at 10 mM in DMSO or 1 mM in EtOH._x000D_ Other Notes_x000D_ Chemical Equivalency 1ea=1mg_x000D_ Legal Information_x000D_ LightOx is a trademark of LightOx Ltd.
