MitoSOX™ Mitochondrial Superoxide Indicator für Lebendzell-Bildgebung

MitoSOX Superoxid-Indikatoren sind neuartige fluorogene Farbstoffe, die speziell auf Mitochondrien in lebenden Zellen abzielen. Oxidation des MitoSOX-Reagenz durch mitochondriales Superoxid erzeugt eine helle grüne oder rote Fluoreszenz.

MitoSOX Green und MitoSOX Red Superoxid-Indikatoren sind neuartige fluorogene Farbstoffe, die speziell auf Mitochondrien in lebenden Zellen abzielen. Oxidation des MitoSOX-Reagenz durch mitochondriales Superoxid erzeugt eine helle grüne oder rote Fluoreszenz.
Leistungsmerkmale dieser Indikatoren sind:
• Sie werden leicht durch Superoxid, jedoch nicht durch andere reaktive Sauerstoffspezies (ROS) und reaktive Stickstoffspezies (RNS) generierende Systeme oxidiert.
• Verwendung für die Bildgebung lebender Zellen
• Schnelle und selektive gezielte Anwendung auf Mitochondrien
• MitoSOX Green Indikator: ∼488/510 nm Absorptions-/Emissionsmaxima (herkömmlicher FITC/GFP-Filtersatz)
• MitoSox Red Indikator: ∼396/610 nm* Absorptions-/Emissionsmaxima (benutzerspezifischer Filtersatz empfohlen)

*Robinson et al (1) berichten, dass bei Anregung des Farbstoffs MitoSOX Red bei 396 nm anstelle von 510 nm dieser ein selektiverer Marker für mitochondriales Superoxid sein kann.

MitoSOX Green Indikator wird als Einzelfläschchen oder Packung mit fünf Fläschchen angeboten. MitoSOX Red Indikator wird als Einzelfläschchen oder Packung mit zehn Fläschchen angeboten. Eine Packung mit je einem Fläschchen der Indikatoren MitoSOX Red und MitSOX Green ist ebenfalls erhältlich.

Schneller, einfacher Nachweis von mitochondrialem Superoxid in lebenden Zellen
Die Produktion von Superoxid durch Mitochondrien lässt sich in der Fluoreszenzmikroskopie mithilfe von MitoSOX Superoxid-Indikatoren visualisieren. Sie durchdringen lebende Zellen, und lagern sich selektiv an Mitochondrien an. Sie werden schnell durch Superoxid, jedoch nicht durch andere reaktive Sauerstoffspezies (ROS) und reaktive Stickstoffspezies (RNS) oxidiert. Das oxidierte Produkt fluoresziert stark.

Mithilfe von MitoSOX Indikatoren lassen sich Artefakte isolierter mitochondrialer Präparate aus direkten Messungen von Superoxid unterscheiden, das in den Mitochondrien lebender Zellen erzeugt wird. Es kann auch ein wertvolles Hilfsmittel für Untersuchungen von Substanzen sein, die oxidativen Stress in verschiedenen Krankheitsbildern beeinflussen. Darüber hinaus kamen diese Indikatoren auch in Stoffwechselflussassays mit High-Content-Instrumenten (2) zum Einsatz. MitoSOX-Indikatoren wurden auch zum Nachweis von mitochondrialem Superoxid mit Durchflusszytometrie (3) verwendet.

Häufig gestellte Fragen (FAQ)

Are MitoSOX Mitochondrial Superoxide Indicators fixable?

MitoSOX indicator-stained cells should be imaged within 2 hr and are not fixable.

What is the shipping temperature for MitoSOX Mitochondrial Superoxide Indicators, for live-cell imaging?

MitoSOX Mitochondrial Superoxide Indicators, for live-cell imaging are shipped at ambient temperature and should be stored as recommended.

Why was the excitation wavelength for MitoSOX Red (Cat. Nos. M36008, M36007, M36009) changed from 510 nm to 396 nm in the new manual? What is the optimal wavelength to measure the signal?

The excitation wavelength for MitoSOX Red (Cat. Nos. M36008, M36007, M36009) was changed from 510 nm to 396 nm in the new manual because we have found that excitation at 396 nm selectively excites the superoxide oxidation product without exciting other non-specific products.  Although the indicator displays an adequate signal when excited at 510 nm, we highly recommend using the 396 nm excitation wavelength for selective detection of the indicator’s response to mitochondrial superoxide. For more information on the selective detection of superoxide at 396 nm, please refer to the article linked below.

Robinson KM, Janes MS, Pehar M, Monette JS, Ross MF, Hagen TM, Murphy MP, Beckman JS. Selective fluorescent imaging of superoxide in vivo using ethidium-based probes. Proc Natl Acad Sci U S A. 2006 Oct 10;103(41):15038-43. doi: 10.1073/pnas.0601945103. Epub 2006 Oct 2. PMID: 17015830; PMCID: PMC1586181.

The optimal emission wavelength to observe the superoxide oxidation product is 580 nm. Please note that the 610 nm wavelength mentioned in the MitoSOX Green and MitoSOX Red Mitochondrial Superoxide Indicators User Guide is incorrect.

We suggest a working concentration range of 100 nM to 5 µM.  It is recommended to optimize the final working concentration for each sample and application. It is important to be cautious when using concentrations >1 µM, as higher non-specific labeling may occur as well as possible mitochondrial toxicity.

Can I store stock solutions of MitoSOX Mitochondrial Superoxide Indicators (Cat. Nos. M36005, M3006, M36007, M36008, M36009) beyond one day?

No. We do not recommend storing MitoSOX Mitochondrial Superoxide Indicators (Cat. Nos. M36005, M3006, M36007, M36008, M36009) stock solutions beyond one day as they are more susceptible to spontaneous oxidation (from radicals in the atmosphere) when in solution compared to storing the reagents in solid form.

Superoxide dismutase mimetics: synthesis and structure-activity relationship study of MnTBAP analogues.

PubMed ID:12110324
Carboxylic ester and amide-substituted analogues of [5,10,15,20-tetrakis(4-carboxyphenyl)-porphyrinato]manganese(III) chloride (MnTBAP) were synthesized and assayed as potential superoxide dismutase (SOD) mimetics. The tetraester analogues 4a and 4b were found to have comparable SOD activity to the known SOD mimetic MnTBAP, while amides 4c-4e exhibited reduced SOD activity. In the substituted methyl benzoate/acid ... More
