Fluorescent probes target specific cellular and sub-cellular components, or they may selectively target a single biomolecule. Alternatively, they might provide a functional read-out, such as live versus dead cell staining. They enable researchers to detect particular components of complex biomolecular assemblies, such as microtubules, with high sensitivity and selectivity allowing the exploration of cell structure and function. R&D Systems portfolio offers a wide selection of fluorescent probes, covering organelle probes and cell viability stains.

MitoBrilliant™ Dyes
MitoBrilliant are next-generation fluorescent stains for the localization and tracking of mitochondria in both live and fixed cells. Our range harnesses Janelia Fluor® dye technology, conferring some of the properties that make these widely used dyes, into mitochondrial stains. The MitoBrilliant Live dyes accumulate in the mitochondria of live cells. Two dyes are available: MitoBrilliant™ Live 646 and MitoBrilliant™ Live 549. A universal stain for mitochondria in both live and fixed cells is also available: MitoBrilliant™ 646.

* In live-cell staining, Δψm drives initial recruitment of the dye into mitochondria. After staining, localization of the dyes becomes insensitive to Δψm changes. In pre-fixed cell staining, MitoBrilliant™ 646 can localize and stay in mitochondria without Δψm.
