    The protective role of p38 MAPK inhibition in II/R-induced ALI and regulation of AQP4 in rats. HE staining and Lung wet/dry weight ratio show obvious evidences of ALI and lung edema. Western blot and immunofluorescent staining confirm the increased expression levels of AQP4 and P-p38 MAPK protein in the lung tissues. Then, the p38 MAPK inhibitor is administrated intraperitoneally. Results show that p38 MAPK inhibition downregulates AQP4 expression in the lungs and protected lung from acute injur

    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 (6.79 mM); Clear solution

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

      Add each solvent one by one:  10% DMSO    90% Corn Oil

      Solubility: ≥ 2.5 mg/mL (6.79 mM); Clear solution

      This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.

      Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL Corn oil, and mix evenly.

    Help & FAQs
    • Do most proteins show cross-species activity?

      Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
