Compared to genomics, the analysis of proteome is rather difficult since in human cells there are around 200000 proteins, which are expressed at any time at different levels of concentration with a wide dynamic range. In addition, a given proteome is not static but dynamic, being defined by a combination of the cell's genome, environment, and even its history. To meet the higher and higher requirements from proteome analysis, in our recent work, we have developed some capillary electrophoresis (CE)-based techniques for the analysis of complex protein samples.展开更多
