Biological ActivityMitoBrilliant 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.
MitoBrilliant™ 646 is a next-generation universal stain for mitochondria in both live and fixed cells. It is retained in mitochondria following fixation with exceptionally clear staining and is retained in the mitochondria of live cells following loss of the mitochondrial membrane potential. Additionally, MitoBrilliant™ 646 can be used to stain pre-fixed cells/tissue, making this dye suitable for IHC/ICC.
Two dyes that accumulate in the mitochondria of live cells in a mitochondrial membrane potential (Δψm) dependent manner are also available: MitoBrilliant™ Live 646 (red emission) and MitoBrilliant™ Live 549 (yellow/orange emission).
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.
