Product Details

Biological Activity

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.
