毛细管电泳及其应用(capillaryelectrophoresis,CE)
一、毛细管电泳的概述：毛细管电泳又称高效毛细管电泳，它是在熔融的石英毛细管（内径为25~100m）中进行电泳，其管内填充缓冲液或凝胶，是近年来进展最快的分析方法之一。毛细管电泳是电泳技术和现代微柱分离相结合的产物，它具有效率更高、速度更快、样品和试剂消耗量特少的特性。毛细管电泳仪的基本结构：1、 高压电极槽与进样机构 2、填灌清洗机构 3、毛细管 4、检测器 5、铂丝电极 6、低压电极槽 7、恒温机构 8、记录/数据处理毛细管的结构：毛细管电泳通常使用内径为25~100μm的弹性（聚酰亚胺）涂层熔融石英管。 毛细管的特点是：容积小；侧面/截面积大而散热快、可承受高电场；可使用自由溶液......阅读全文
