gA White to off-white solid. Naturally-occurring ion channel-forming pentadecapeptide. The association of two gA peptides causes the formation of a monovalent cation-selective ion channel. Causes K+/H+ exchange in mitochondria in a non-voltage dependent manner. Causes red blood cell lysis at 0.5-1.0 µg/ml. Purity: ≥95% by HPLC. Contaminants: gB and gC isomers: <1% by HPLC.
