    References - Scientific background
      • Pardaxin is a 33 amino acid peptidyl toxin, produced by the Red Sea Moses sole fish Pardachirus marmoratus. Pardaxin is acidic, amphipathic, and hydrophobic that forms voltage-dependent pore channels in liposomes and planar lipid bilayers and living cells2.

        The toxin exhibits a neurotoxic, excitatory activity toward neurons at subcytotoxic concentrations by both Ca2+-dependent and Ca2+-independent mechanisms. Pardaxin also causes hemolysis, reduction of blood pressure, cell death by necrosis, and is lethal to rats at higher concentrations3.
