Tetrodotoxin (TTX) reversibly blocks excitable sodium channels and has been a widely used tool for studies of excitable membranes of nerve, skeletal and cardiac cells. Biotium offers high quality tetrodotoxin at a competitive price. Tetrodotoxin citrate free can be dissolved in slightly acidic buffer. TTX also is available with citrate (catalog no. 00061), which can be dissolved in water to obtain TTX in pH 4.8 citrate buffer.
