    Cell Assay
    [2]

    ESCs are plated in 96-well plates at a concentration of 1×103cells/well. After attachment, cells are treated with different doses of metformin/compound C for 0 min, 15 min, 1 h, and 24 h. MTT assays are performed as described previously. In brief, MTT (5 mg/mL) is added to the 96-well plates at a volume of 10 μL/well, and the plates are incubated for 4 h. The MTT reaction is terminated by removal of the culture medium containing MTT, and 100 μL DMSO per well are added and incubated at RT on a shaker for 10 min to ensure that the crystals had dissolved sufficiently. Absorbance values are measured at 595 nm. Cell proliferation (percentage of control) is calculated as follows: absorbance (experimental group)/absorbance (control group). Cell proliferation inhibition (percentage of control) is calculated as follows: 100%−cell proliferation (percentage of control). Each experiment is performed in duplicate and repeated six times to assess result consistency.

    Animal Administration
    [1]

    The animals are randomized into six groups consisting of six rats each. Rats in group 1 (control) receives a subcutaneous injection of physiological saline (0.5 mL) and are left untreated for the entire experimental period. Rats in group 2 receives an oral administration of metformin (100 mg/kg; twice daily) for 2 days and are subcutaneously injected with saline at an interval of 24 h for 2 consecutive days. Rats in group 3 (MI control) receives an oral administration of saline (twice daily) for 2 days and are sc injected with NSC 37745 (100 mg/kg) daily for 2 consecutive days at an interval of 24 h. Rats in groups 4 to 6 are treated with metformin at 25, 50, and 100 mg/kg. Metformin is dissolved in saline and is gavaged at a volume of 0.25-0.5 mL twice a day at an interval of 12 h, started immediately before NSC 37745 injection.

    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.
