• Brand: TRC
• Description: Stability Light SensitiveApplications One of the catechin isomers and a potent antioxidant that can modulate a wide range of membrane proteins. Its bilayer-modifying potency was tested using gramicidin A (gA) channels as probes. All the catechins alter gA channel function and modify bilayer properties, with a 500-fold range in potency. The gallate group causes current block, as evident by brief downward current transitions.References Ingolfsson, H., et al.: FEBS Lett., 585, 3101 (2011),
