MitoBrilliant™ Live 646
Purity: ≥95%
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.

Scientific Data

Live-cell image of mitochondria stained with MitoBrilliant™ Live 646 HeLa cells were incubated with MitoBrilliant™ Live 646 (100 nM) for 40 minutes and counter stained with DAPI (Catalog # 5748). Image was taken using an LSM880 Confocal using a 63x objective. Scale bar = 10 µm.
