Gel- based proteomics is one of the most versatile methods for fractionating protein complexes. Among these methods, two dimensional- polyacrylamide gel electrophoresis (2-DE) represents a mainstay orthogonal approach, which is popularly used to simultaneously fractionate, identify, and quantify proteins when coupled with mass spectrometric identification or other immunological tests. Although 2-DE was first introduced more than three decades ago, several challenges and limitations to its utility still exist. This review discusses the principles of 2-DE as well as both recent methodological advances and new applications.
基于凝胶的蛋白质组学是分离蛋白质复合物最通用的方法之一。在这些方法中,二维聚丙烯酰胺凝胶电泳(2-DE)是一种主要的正交方法,当与质谱鉴定或其他免疫测试结合使用时,它被广泛用于同时分离、鉴定和定量蛋白质。尽管2-DE在三十多年前就首次被引入,但它在实用性方面仍然存在一些挑战和局限性。本文综述了2-DE的原理以及最近的方法进展和新应用。
