河鲀毒素(Tetrodotexin,TTX)在神经生物学及其它很多领域中对于阻断机体兴奋组织的Na~+通道和由Na~+通道产生的动作电位均为一种必不可少的重要工具药。过去,TTX唯一的商品来源是日本三共公司。因此这样一种重要物质,如果能出现又一新的来源,这对于科学工作者来说,无论是在经济价格方面,还是产品的质量及效力方面都具有潜在的好处。中华人民共和国河北省水产研究所最近生产了商品化TTX。我们获得了一小部分试验样品,在此报道中国TTX与日本三共TTX Tetrodotexin (TTX) is an indispensable and important tool in neurobiology and many other fields to block the Na ~ + channel of excitatory tissue and the action potential generated by Na ~ + channel. In the past, TTX’s only source of goods is Japan’s Sankyo. Therefore, if another important source of such an important substance emerges, this will have potential benefits to scientists in terms of economic prices and the quality and effectiveness of the products. People’s Republic of China Hebei Institute of Fisheries recently produced commercial TTX. We have obtained a small sample of the test, here reported that China TTX and Japan Sankyo total TTX
