A two-dimensional gel electrophoresis (2D-GE) and capillary isoelectric focusing (cIEF) were performed sub-sequently to analyze protein mixtures from laboratory animal tissues (liver, muscle, and mammary gland). Both tech-niques were compared and evaluated. It was found that cIEF can be a valuable alternative in comparison to 2D-GE. Espe-cially considering the goals associated with the determination of far the separated proteins, cIEF possesses perspective analytical advantages.
