双向电泳技术应用于消化道粘膜组织并优化
Application and Optimization of Two-dimensional Gel Electrophoresis for Proteomics of Digestive Tract Mucosa
摘要
目的 :初步建立并优化了组织蛋白质组分析所需的双向电泳技术 ,提高其分辨率及重复性。方法 :以小鼠肠组织为例 ,对以固相pH梯度为第一向的双向电泳的关键因素与环节 ,如样品处理、上样量、电泳参数、凝胶浓度和SDS凝胶电泳染色方法等进行一系列的优化。结果与结论 :以固相pH梯度—IPG胶条 (pH 3~ 10 )进行第一向等电聚焦 ,以SDS均一胶 (13% )的垂直电泳为第二向 ,成功地得到了肠组织的双向电泳图谱。
