    生物活性

    Melittin free acid is a basic 26-amino-acid polypeptide, the major active ingredient of honeybee venom. Melittin free acid is an activator of phospholipase A2 (PLA2). Melittin free acid has broad-spectrum antifungal activity with MIC values of 0.4-60 μM. Melittin free acid hinders fungal growth by inducing cell apoptosis, repressing (1,3)-β-D-glucan synthase and participating in other pathways[1][2].

    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.
