Tetrodotoxin with citrate

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 with citrate is a lyophilized mixture of 1 mg high purity TTX and 5 mg pH 4.8 citrate buffer, which can be dissolved in water to obtain TTX in pH 4.8 citrate buffer.  TTX also is available in citrate-free form (catalog no. 00060), which can be dissolved in a slightly acidic buffer (pH 4.8) of your choice.
