电鳐是n-胆硷受体(n-AChR)最丰富的来源。关于我国南海产的黑斑双鳍电鳐国内外报道很少,利用受体蛋白来研究抗蛇伤中草药的抗毒作用在文献中也未曾见到。本文介绍该鱼受体膜的分离纯化及其活性测定,并对广东蛇药抗蛇毒作用原理在分子水平进行探讨研究。 Electroencephalography is the most abundant source of n-choline receptors (n-AChRs). About China’s South China Sea production of black spot double fin electricity 鳐 very few reports at home and abroad, the use of receptor proteins to study the antitoxic effect of anti-snake Chinese herbal medicine has not been seen in the literature. This article describes the fish receptor membrane separation and purification and determination of activity, and anti-snake venom in Guangdong snake venom at the molecular level to explore the principle.
