Purification and analysis of AT-toxin Firstly, we detected the components of protein and nonprotein, the results showed that AT-toxin is a nonprotein. We have carried out the liquid chromatogram analysis of the toxin. The result indicates that there are many components in this toxin and there are four kinds of components which content is more than others. At last, we have the experiment of separating the cpmpositions with the silica gel and we get four components which are active.
AT-毒素的初步纯化与分析为确定AT-毒素的组分,首先对毒素的蛋白质和非蛋白质组分的毒性进行了测定,结果表明:AT-毒素活性组分为非蛋白质;对毒素进行硅胶G薄层层析,初步分离得到10种组分,其中四种组分具有活性:组分Ⅵ、Ⅶ、Ⅷ、Ⅸ,初步说明了该毒素含有多种组分;进一步对该毒素进行液相色谱分析,也发现该毒素含多种组分,其中四种组分峰高和峰面积较大,含量较高;其致毒活性可能是由这些组分协同作用的结果,它们之间可能存在正协同或负协同作用关系。
