LysoView™ dyes label lysosomes in live cells, and are available with blue, green, visible red, and far-red fluorescence. Far-red LysoView™ 650 is compatible with super-resolution imaging by STED and SIM. Note: LysoView™650 (70059 and 70059-T) is temporarily unavailable.
Light-on LysoView™ 555
Light-On LysoView™ 555 is a red fluorogenic lysosome dye with pH-dependent fluorescence. Light-On LysoView™ dye is unique among commercially available lysosomotropic dyes in that its fluorescence in cells is activated by exposure to UV excitation.
MitoView™ dyes are fluorogenic mitochondrial stains for live cells. The dyes rapidly accumulate in mitochondria and can be imaged without washing. They are available with blue, green, far-red, and near-infrared fluorescence.
NucSpot® Live Cell Nuclear Stains
NucSpot® Live Cell Nuclear Stains are cell-membrane permeable DNA dyes that specifically stains nuclei in live or fixed cells. They have excellent specificity for DNA without the need for a wash step, and they have have low toxicity for live cell imaging. Supplied as 1000X stock solutions in DMSO.
