摘要
雷氏大疣蛛是我国最近鉴定的蜘蛛新种 .雷氏大疣蛛毒素 - 就是以其粗毒为材料 ,利用阴、阳离子交换层析和反相 HPLC分离得到并命名的一种新型神经毒素肽 .根据质谱分析得知它的相对分子质量为3 0 2 1 .5 6;通过初步毒性研究 ,证明它是一个神经毒素 .
The spider Macrothele raveni was recently identified as a new species of Genus Macrothele. A new neurotoxic peptide named Raventoxin Ⅱ was isolated from the venom of the spider by means of reverse phase, ion exchange and anion exchange high performance liquid chromatography. The relative molecular mass of the toxin is 3 021.56 on the basis of the analysis of mass spectrum. According to its preliminary toxic research, it has been proved that it is a neurotoxin.
