Indicadores de superóxido mitocondrial MitoSOX™, para adquisición de imágenes de células vivas

Los indicadores de superóxido MitoSOX son colorantes fluorogénicos novedosos dirigidos específicamente a las mitocondrias en células vivas. La oxidación del reactivo MitoSOX por superóxido mitocondrial produce una fluorescencia verde o roja brillante.

Los indicadores de superóxido MitoSOX Green y MitoSOX Red son colorantes fluorogénicos novedosos dirigidos específicamente a las mitocondrias en células vivas. La oxidación del reactivo MitoSOX por superóxido mitocondrial produce una fluorescencia verde o roja brillante.
Las características de estos indicadores incluyen:
• Fácilmente oxidado por superóxido, pero no por otros sistemas generadores de ROS o RNS
• Uso para la adquisición de imágenes de células vivas
• Dirigido de manera rápida y selectiva a las mitocondrias
• Indicador MitoSOX Green: absorción/emisión máxima de ∼ 488/510 nm (conjunto de filtros FITC/GFP tradicionales)
• Indicador MitoSOX Red: absorción/emisión máxima de ∼ 396/610 nm* (se recomienda conjunto de filtros personalizado)

*Robinson et al. (1) informó que si el colorante MitoSOX Redse excita a 396 nm en lugar de 510 nm, puede ser un marcador más selectivo para el superóxido mitocondrial.

El indicador MitoSOX Green se ofrece como un vial o un paquete de cinco viales. El indicador MitoSOX Red se ofrece como un vial o un paquete de diez viales. También hay disponible un paquete variado de un vial con cada uno de los indicadores MitoSOX Red y MitoSOX Green.

Detección rápida y sencilla del superóxido mitocondrial en células vivas
La producción de superóxido por parte de las mitocondrias se puede visualizar en microscopía de fluorescencia utilizando indicadores de superóxido MitoSOX. Impregnan células vivas donde se dirigen selectivamente a las mitocondrias. Se oxidan rápidamente por superóxidos, no por otros sistemas de generación de especies reactivas de oxígeno (ROS) y de especies reactivas de nitrógeno (RNS). El producto oxidado es altamente fluorescente.

Los indicadores MitoSOX pueden utilizarse para distinguir artefactos de preparaciones mitocondriales aisladas de mediciones directas de superóxidos generados en las mitocondrias de las células vivas. Asimismo, pueden constituir una herramienta útil para la investigación de los agentes que modulan el estrés oxidativo en diversas enfermedades. Además, estos indicadores se han utilizado en ensayos de flujo metabólico mediante instrumentos de alto contenido (2). Los indicadores MitoSOX también se han utilizado para detectar superóxido mitocondrial mediante citometría de flujo (3).

Preguntas frecuentes

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.

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
