    Cell viability of BMDMs treated with Epalrestat (2.5-200 μM) for 24 h as detected using a CCK-8 reagent.

    Epalrestat purchased from MedChemExpress. Usage Cited in: J Transl Med. 2023 Oct 7;21(1):700.  [Abstract]

    LPS-primed BMDMs were treated with various doses of Epalrestat (10, 20, 40 μM) for 1 h before stimulation with nigericin for 30 min. Immunoblot analysis of epalrestat was used to detect cleaved caspase-1 and IL-1β in the cell supernatants (Sup.) and the expression of NLRP3, caspase-1 p45, pro-IL-1β, and ASC in the cell lysates (Lys.).

    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    90% Corn Oil

      Solubility: ≥ 2 mg/mL (6.26 mM); Clear solution

      This protocol yields a clear solution of ≥ 2 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 (20.0 mg/mL) to 900 μL Corn oil, and mix evenly.

    For the following dissolution methods, please prepare the working solution directly. It is recommended to prepare fresh solutions and use them promptly within a short period of time.
    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.

    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.
