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。

The principal purpose of this study is to set up the isolation methods for diphtheria toxin expressed by genes, to purify the toxin with complete biological activities, and to make researches on its toxicities. In the experiments, the target gene was inserted into the cloning vectors--pET22b, then the vectors were introduced into host cells -BL21(DE3). The expression of the toxin was induced by addition of IPTG. The expression products were purified by His-6 label affinity chromatography. Then the diphtheria toxin expressed was transferred to PVC membrane using semidry blotter to determine the amino acid sequence of N-terminal. The "nicked" diphtheria toxin linked by disulfide bond was gained by protease hydrolysis.

Specifically, we will (1) perform electrophysiological study on the interaction of CTXs with cardiomyocytes stripped of specific GAGs,(2) study the binding of CTXs from spitting cobra venom with corneal tissue and examine the possible involvement of GAGs in the disruption of regular superstructure of collagen fibril and (3) examine the role of polyproline peptide sequence of P-type CTXs in the lytic action of CTXs. The results of this study will not only help delineate the mechanism of cobra CTXs, a long standing problem in the toxicity of cobra venom, but also suggest a new approach to develop CTXs into a potential drug for cancer.
