Methods: Fat extracted from food and oil sample was determined directly on the ZnSe crystal cisterna of horizon attenuation total reflection equipment with deuterated triglycine sulfate detector in the FT-IR.

食品中提取的脂肪或油脂样品直接置于红外光谱仪的水平衰减全反射部件的槽式ZnSe晶体上，氘化三甘氨酸硫酸酯检测器检测。

In this experiment, a new method was used to purify the toxin protein produced by Verticillium dahliae. The supernatant of fungus culture was frozen and dried with Lyophilizer first, and then dialysed by Dialysis Membranes (MWCO 1000) after dissolved in distilled water. This method can eliminate the salt and sucrose in culture medium and reserve the protein component almost completely. VD-toxin were analysed using sodium dodecyl sulfate polyacrylamide gel analysis. The results indicated that the protein components were very complex, and included glycoprotein within 35.8kDa-83.2kDa. Furthermore, treatments on glycoproteins with high temperature, conA and proteinase alleviated, not abolished, their activities.NO and H_2O_2 production were assayed in two cultivars of cotton cells which were treated with VD-toxin.

本实验首先确定了用冷冻浓缩后透析的方法初步提纯棉花黄萎病菌毒素，该方法能有效去除粗提毒素中的蔗糖和盐离子并能最大程度的保留黄萎病菌分泌的蛋白成分；对毒素蛋白成分鉴定结果表明蛋白条带多，每种蛋白的含量少，小分子量蛋白含量多，糖蛋白染色结果显示，毒素蛋白中分子量在35.8kDa-83.2kDa之间的蛋白大多数为糖蛋白，分子量小于35.8kDa的蛋白多为非糖蛋白；性质鉴定结果显示，毒素中有活性的蛋白成分具有部分可耐高温高压，且毒素蛋白中的蛋白成分和糖基成分都具有致萎活性。

Dorsalis by salting out, ion exchange chromatography, and gel filtration chromatography. By salting out the egg homogenate, SDS-PAGE analysis revealed that the Vns were mainly precipitated in a 50~70% ammonium sulfate solution. The salted-out proteins were further purified by ion exchange chromatography, and the result showed that Vns were mainly eluted with a 0.3~0.5 M sodium chloride gradient. Finally, the elutes of ion exchange chromatography were refined by running them through gel filtration chromatography to obtain purified Vns. SDS-PAGE separated the 48- and 51-kDa purified Vns, and used them as antigens to raise polyclonal antibodies.
