proteins account for only a small fraction of the total cellular proteome, and since the majority of
ER-associated proteins are membrane proteins, which are especially difficult to purify, proteomic
analysis of the ER has been a challenging endeavor. To facilitate the study of the ER proteome,
an ER-like fraction of small vesicles, termed microsomes,can be isolated from cell homogenates
by differential centrifugation. However, efficiently extracting proteins from this membrane-rich fraction
is difficult, making a comprehensive proteomic analysis of lipid-rich microsomal samples difficult [1].
Here we describe a method for the efficient extraction of proteins from rat liver microsomes, using

利用压力循环技术(笔颁罢)从动物微粒体中提取蛋白
内质网(ER)是一种亚细胞膜网络结构,它位于细胞质并连接着质膜和核膜。一些重要的细胞功能比如蛋白质生物合成、异型生物质的氧化以及蛋白运输 等均发生在内质网(ER)。由于起源于内质网(ER)的蛋白只占细胞蛋白总量的很小一部分,而且大多数与内质网关联的蛋白均是膜蛋白,因此这些蛋白非常难 以纯化,内质网(ER)的蛋白质组学分析也因而变得非常具有挑战性。为了方便内质网(ER)蛋白的研究,一种小囊泡中类似于内质网的片段和微粒体可通过梯 度离心从细胞均质中分离出来。但是,试图从这种膜含量多的片段中有效的提取蛋白是非常困难的,从而对脂质含量多的微粒体样品进行广泛的蛋白质组学分析也变 得非常困难。本文描述了一种有效的从大鼠肝脏微粒体中提取蛋白的方法,该方法正是利用压力循环技术(PCT)和一种特别的ProteoSolve试剂盒。
