Neosaxitoxin (Cat. No: T000026) is a derivative of tetrahydropurine. Saxitoxin (STX) is one of the main toxins of paralytic shellfish poison (PSP). STX interferes with the conduction process of neuromuscular by blocking Na + channels, so that the random muscles are relaxed and paralyzed, resulting in a series of toxic symptoms.
