Abstract
Complex proteome samples require efficient separation and detection methods in order to characterize their protein components. On-line combination of capillary isoelectric focusing (CIEF) with electrospray ionization (ESI) mass spectrometry (MS) is shown as an effective method to analyze complex protein mixtures. Our experience with several microorganisms allowed us to establish successful experimental protocol. Here we use the example of E. coli whole-cell lysate for the CIEF separation and MS detection on the intact protein level. The protocol was further adapted for the analysis of the mixture of noncovalent complexes on the intact complex level.
