Abstract
Recently, we developed a new approach for the selective enrichment of low-abundance compounds in biological samples by capillary electrophoresis. As a model test, the low-abundance compound lysozyme was successfully fractionated from a mixture containing high-abundance compound BSA (1:4500) using a custom-made apparatus. The feasibility of this approach for real complex biological samples was verified by rat serum, wherein three low-abundance proteins with high charge/mass ratios were detected.
