    IC50 & Target

    IC50: 0.37 nM (APJ)[1]
    In Vivo

    Apelin-13 (200 μg/kg; IP, daily for 4 weeks) improves cardiac function, improves insulin resistance, improves lipid metabolism, significantly decreases TNF-α and leptin on serum, induces the expression of Apelin-12 in serum and markedly elevates GLUT4 and p-AMPKα2 levels[2].
    Apelin-13 (10 and 100 μM; ICV, single dosage) increases the spontaneous discharges in the majority of pallidal neurons[4].

    MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

    Animal Model: Goto-Kakizaki (GK) rats (12 weeks old; 240-280 g; fed with a high-fat diet: 66.5% standard chow, 10% lard, 20% sucrose, 2.5% cholesterol and 1% pig bile salt)[2]
    Dosage: 200 µg/kg
    Administration: IP, daily for 4 weeks
    Result: Significantly decreased heart rate; lowered the levels of fasting plasma glucose (FPG), fasting insulin (FINS) and homeostasis model assessment for insulin resistancey (HOMA-IR); decreased serum levels of total cholesterol (TC), triglyceride (TG) and low density lipoprotein-cholesterol (LDL-C) and increased high density lipoprotein-cholesterol (HDL-C); decreased NO level, cNOS activity, TNF-α and leptin in serum; induced the expression of Apelin-12.
    Animal Model: Adult Wistar rats (SPF, 8-10 weeks, 240-280 g)[4]
    Dosage: 10 and 100 μM
    Administration: ICV, single dosage
    Result: Increased the spontaneous discharges in the majority of pallidal neurons.

    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.
