摘要:

電泳儀可分為:
     1、毛細管電泳儀:其主要部件有0~30kV可調穩壓穩流電源,內徑小于100μm(常用50~75μm)、長度一般為30~100cm的彈性石英毛細管、電極槽、檢測器和進樣裝置。檢測器有紫外/可見分光檢測器、激光誘導熒光檢測器和電化學檢測器,前者*為常用。進樣方法有電動法(電遷移)、壓力法(正壓力、負壓力)和虹吸法。成套儀器還配有自動沖洗、自動進樣、溫度控制、數據采集和處理等部件。
     2、常規電泳儀:其組成部件為可調穩壓穩流電源,垂直電泳槽,水平電泳槽,電極連接線,支持體【非凝膠性支持體區帶電泳 (支持體有: ①淀粉②纖維素粉 ③玻璃粉,硅膠等) ;凝膠支持體區帶電泳支持體有: ①淀粉液 ②聚丙烯酰胺凝膠 ③瓊脂(糖)凝膠】;陶瓷板,抽水泵,輸水管,冰水曹等部件組成。
      3、其(qi)他電(dian)(dian)(dian)泳(yong)(yong)儀:Tiselius或微(wei)量電(dian)(dian)(dian)泳(yong)(yong) 、顯微(wei)電(dian)(dian)(dian)泳(yong)(yong)、等(deng)電(dian)(dian)(dian)點聚焦電(dian)(dian)(dian)泳(yong)(yong)技術 、等(deng)速電(dian)(dian)(dian)泳(yong)(yong)技術、密(mi)度(du)梯度(du)電(dian)(dian)(dian)泳(yong)(yong)等(deng)。是一種非支持體(ti)的電(dian)(dian)(dian)泳(yong)(yong)儀也稱為(wei)自(zi)由電(dian)(dian)(dian)泳(yong)(yong)法的發展并不迅速,因為(wei)其(qi)電(dian)(dian)(dian)泳(yong)(yong)儀構造復雜(za)、體(ti)積(ji)龐大,操作要求嚴格,價格昂貴等(deng)很少使用。

電泳的分類:
    根據電泳儀原理、電泳儀功能、電泳儀的使用方法、電泳儀的用途不同可以為:瓊脂糖凝膠電泳、毛細管電泳、凝膠電泳、聚丙烯酰胺凝膠電泳、醋酸纖維薄膜電泳、高效毛細管電泳、瓊脂糖電泳、SDS-PAGE凝膠電泳、蛋白質電泳、血清蛋白電泳、dna電泳、血紅蛋白電泳、蛋白質雙向電泳、**電泳、等電聚焦電泳、單細胞凝膠電泳、蛋白質凝膠電泳、質粒電泳、對流**電泳、變性電泳等。
