Product Description
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.
Key information: MitoBrilliant™ 646 is a red-fluorescent mitochondrial stain for both live and fixed cells.
Used for: mitochondrial staining for both live and fixed cells/tissue.
Application: flow cytometry, super-resolution microscopy-STED, high content screening, IHC/ICC.
Properties and Photophysical Data: MitoBrilliant™ 646 is retained in mitochondria with exceptionally clear staining and is retained in the mitochondria of live cells following loss of the mitochondrial membrane potential. Excitation and emission maxima (λ) are 655 nm and 668 nm, respectively; extinction coefficient = 125,000 M-1cm-1.
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.

Species: HumanVerified Customer | Posted 11/20/2023MitoBrilliant™ 646 produced excellent results as both a live and fixed cell stain. As a live cell stain MitoBrilliant™ 646 produced a stable signal within 20 minutes. For use as fixed-cell stain optimal conditions were found to be a 1-hour incubation in live cells followed by fixation with ice-cold acetone-methanol.Fixed-cell image of mitochondria stained with MitoBrilliant™ 646: Dermal fibroblast cells were incubated with MitoBrilliant™ 646 (100 nM) for 1 hour at 37°C, fixed with ice-cold acetone-methanol (1:1) and counterstained with Hoechst 33342.
