    제품 설명

    N-Lactoyl-phenylalanine is a blood-derived signaling metabolite that can be induced by exercise. N-Lactoyl-phenylalanine can reduce obesity and improve glucose tolerance[1].

    In Vivo

    N-Lactoyl-phenylalanine (50 mg/kg, i.p.,once a day for 10 days) specifically suppresses energy intake in obese mice without affecting energy expenditure pathways, and this effect is not observed in lean mice[1].

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

    Animal Model: Diet-induced obese (DIO) mice model[1]
    Dosage: 50 mg/kg
    Administration: Intraperitoneal (i.p.), once a day for 10 days
    Result: Resulted in reduced cumulative food intake and reduced body weight compared with control mice. After 10 days, mice treated with N-Lactoyl-Phenylalanine also exhibited improved glucose homeostasis, and reduced adiposity without any changes in the weights of the other organs.

    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.
