Biological Activity for MitoBrilliant™ Live 549

MitoBrilliant probes have been developed to overcome some common limitations encountered with standard mitochondrial trackers, offering clearer answers to scientific questions. They are next-generation fluorescent stains for the localization and tracking of mitochondria in both live and fixed cells. The 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 in a mitochondrial membrane potential (Δψm) dependent manner. Upon loss of the mitochondrial membrane potential, the dyes disperse, and so provide a dynamic assessment of the mitochondrial membrane potential in live cells. Two dyes are available: MitoBrilliant™ Live 646 (red emission) and MitoBrilliant™ Live 549 (yellow/orange emission).

A universal stain for mitochondria in both live and fixed cells is also available: MitoBrilliant™ 646.

Please refer to the protocol for guidelines on product use, and download the MitoBrilliant Product Guide to view data for each of the dyes in different applications.

Novel Live-cell and Fixable Mitochondrial Probes Poster

Novel Live-cell and Fixable Mitochondrial Probes Poster

Fluorescent probes that accumulate in the mitochondria are useful tools to explore mitochondrial function and cell health. This poster reports the development inhouse and characterization of novel fluorescent probes, known as MitoBrilliant that specifically localize to mitochondria due to mitochondrial membrane potential. The probes are suitable for live or fixed cell staining. The data demonstrate the specificity and enhanced properties of our MitoBrilliant dyes and their use in a range of applications. This poster was presented at CYTO 2022, June 2022, Philadelphia, USA.
