    • The one and two-dimensional separation of proteins extending through the membrane (membrane proteins) is a prerequisite for a complete analysis of the proteome of a functionally intact cell organelle. A substantial drawback of prior art methods for separating is that their applicability is limited to peripheral water-soluble proteins. The aim of the novel method is to electrophoretically separate membrane proteins in one or two dimensions. To this end, membranes from cell organelles, whose membrane protein stock should be separated, are placed on planar supports whose surface was modified using suitable methods in such a manner that the membrane proteins maintain their ability to laterally diffuse in the membrane plane after being placed on the support. By subsequently applying electrical fields, the proteins can be electrophoretically displaced in the membrane plane and, as a result, can be separated in one or two dimensions according to their different charge characteristics.
    • 跨膜蛋白(膜蛋白)的一个维和二维分离为功能完整的细胞器的蛋白质组的完整分析的先决条件。 分离的以前的方法的基本缺点在于,它们的应用被限制在外围,水溶性蛋白质。 新过程的目的是膜蛋白在一个或两个维度的电泳分离。 为了这个目的,细胞器的膜,该膜蛋白放养是要被分离,被施加到其表面已经通过合适的方法改性,以使膜蛋白保留其应用到载体后,横向在膜面内扩散的能力平面的载体。 通过电场的后续申请,在薄膜层中的蛋白质可以根据其不同的电荷特征电泳移动,并且关闭或者在两个维度上分离。
