    In Vitro

    EX229 is a potent and allosteric activator of AMP-activated protein kinase (AMPK), with Kds of 0.06 μM, 0.06 μM and 0.51 μM for α1β1γ1, α2β1γ1 and α1β2γ1, respectively.[1]. Treatment of hepatocytes with EX229 (991) alone results in a slight increase in the phosphorylation of AMPK and RAPTOR only at 0.3 μM, whereas a robust increase in ACC phosphorylation is readily observed and saturated at a concentration of 0.03 μM EX229. AICAR or C13 alone robustly increases T172 phosphorylation of AMPKα, and when EX229 is coincubated, there is a modest additional dose-dependent increase in AMPKα phosphorylation. RAPTOR phosphorylation is modestly increased by AICAR or C13 alone, and it is dose dependently increased when coincubations are carried out with EX229. EX229 also dose dependently (0.01 and 0.1 μM) inhibits lipogenesis (34% and 63%, respectively), which is further reduced when it is coincubated with a low dose of AICAR (0.03 mM) or C13 (1 μM). Treatment with EX229 promotes dose-dependent increases in ACC and RAPTOR phosphorylation. Similar to the observations in hepatocytes[2].

    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: ≥ 1.3 mg/mL (3.01 mM); Clear solution

      This protocol yields a clear solution of ≥ 1.3 mg/mL (saturation unknown).

      Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (13.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.

      Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
    • Protocol 2

      Add each solvent one by one:  10% DMSO    90% (20% SBE-β-CD in Saline)

      Solubility: ≥ 1.3 mg/mL (3.01 mM); Clear solution

      This protocol yields a clear solution of ≥ 1.3 mg/mL (saturation unknown).

      Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (13.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.

      Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.

    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.
