  4. MitoSOX Red

MitoSOX Red is a live cell fluorescent probe that specifically targets mitochondria and is cell membrane permeable. MitoSOX Red enters mitochondria and is oxidized by superoxide but not by other ROS or RNS generating systems. The oxidized MitoSOX Red then binds to nucleic acids in mitochondria/nucleus, producing strong red fluorescence. MitoSOX Red can be used as a fluorescent indicator to specifically detect superoxide. In addition, superoxide dismutase (SOD) can prevent the oxidation of MitoSOX Red.

    In Vitro

    General Protocol

    1. Preparation of MitoSOX Red working solution
    1.1 Preparation of the stock solution
    Dissolve 50 μg MitoSOX Red in 13 μL DMSO to obtain 5 mM of stock solution.
    Note: It is recommended to store the stock solution at -20°C and -80°C away from light and avoid repetitive freeze-thaw cycles.
    1.2 Preparation of MitoSOX Red working solution
    Dilute the stock solution in serum-free cell culture medium or PBS to obtain 1-10 μM of working solution.
    Note: Please adjust the concentration of MitoSOX Red working solution according to the actual situation.
    2. Cell staining
    2.1 Suspension cells（6-well plate）
    a. Centrifuge at 1000 g at 4°C for 3-5 minutes and then discard the supernatant. Wash twice with PBS, 5 minutes each time.The cell density is 1×106/mL.
    b. Add 1 mL of working solution, and then incubate at room temperature for 5-30 minutes.
    c. Centrifuge at 400 g at 4°C for 3-4 minutes and then discard the supernatant.
    d. Wash twice with PBS, 5 minutes each time.
    e. Resuspend cells with serum-free cell culture medium or PBS. Observation by fluorescence microscopy or flow cytometry.
    2.2 Adherent cells
    a. Culture adherent cells on sterile coverslips.
    b. Remove the coverslip from the medium and aspirate excess medium.
    c. Add 100 μL of working solution, gently shake it to completely cover the cells,and then incubate at room temperature for 5-30 minutes.
    d. Wash twice with medium, 5 minutes each time. Observation by fluorescence microscopy or flow cytometry.

    Storage
    -20°C, 1 year. Protect from light

    Precautions

    In Vivo:

    Select the appropriate dissolution method based on your experimental animal and administration route.

    For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
    To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day.
    The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

    • Protocol 1

      Add each solvent one by one:  10% DMSO    40% PEG300    5% Tween-80    45% Saline

      Solubility: ≥ 2.5 mg/mL (3.29 mM); Clear solution

      This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
