title: Recent applications of capillary isoelectric focusing.
abstract: After the advent of capillary isoelectric focusing (CIEF) in the 80's several approaches have been developed in order to use the technique in routine analyses. The recent years showed an extensive increase in the applications of this technique employing its exceptionally high-resolution power. Methodological improvements, as well as hyphenation with other electrophoretic and chromatographic separation procedures, proved the versatility of CIEF in studies of clinically important proteins, recombinant product, cell lysates and other complex mixtures. The combination of CIEF with mass spectrometry detection is one of the major challenges for studying proteomics. This review collected the recent applications of CIEF including innovations in the experimental setup, remedies for the presence of salts in samples, calibration of the pH gradient, carrier ampholyte-free isoelectric focusing, the progress in micropreparation, two-dimensional separations, etc.
