纯化的

Plant Virology 2 S T. H. Chen, FThe course will give conventional and molecular level of plant viruses in order to help the students to get much theoretical and practical knowledge about plant virology. The contents cover the molecular structure of virion and genome, virus isolation, dentification and purification, transmission, variation,ecology, nomenclature and classification, diagnosis and control.

本课程除传统植物病毒学范畴外，并涵盖从分子层次讨论植物病毒之构造，引起之植物病害，田间发生及防治，期能达到理论与实务并重；内容包括植物病毒分子层次的构造及核酸组成，病毒分离、鉴定与纯化，在寄主体内之增殖及转移，媒介传播、遗传及变异，其引起之病害及田间发生生态与防治。

During the incubation of purified α-synuclein with fructose or glucose, it was observed that the protein intrinsic fluorescence at 308 nm decreased while the fluorescence of glycated derivant at 447 nm increased.

将纯化后的α-synuclein分别与果糖和葡萄糖孵育，通过内源荧光、非酶糖基化衍生物特征荧光、圆二色光谱以及电子显微镜等技术进行检测发现：α-synuclein 与还原糖共同孵育后，308 nm内源荧光强度明显降低，同时在447 nm产生一个非酶糖基化衍生物特征荧光。
