Abstract
Two-dimensional gel electrophoresis (2-DE) is a technique that has been widely applied in a variety of proteomics studies. It is capable of resolving complex protein mixtures into individual protein spots based on their isoelectric point and molecular weight, enabling large-scale analysis of protein expression patterns for deciphering their changes in different biological conditions. 2-DE is a powerful tool that empowers researchers to perform differential qualitative and quantitative proteome analysis and is particularly advantageous for characterizing protein isoforms and post-translationally modified proteins. Despite its popularity as the workhorse for proteomics in the past few decades, it has been gradually displaced by the more sophisticated and high-performance mass spectrometry-based methods. However, there are several variations of the 2-DE technique that have emerged as promising approaches that shine new light on specific niches that 2-DE could still contribute. In this review, we first provide an overview of the applications of 2-DE, its merits and pitfalls in the current proteomic research arena, followed by a discussion on several alternative approaches for potential future applications. © 2019 Elsevier B.V
