skintific-peptide Capillary electrophoresis of proteins and peptides stands as a cornerstone in modern analytical chemistry, offering a powerful and versatile platform for the separation and characterization of biomolecules. This high-resolution technique has revolutionized how scientists approach the analysis of complex biological samples, providing rapid and precise insights into the intricate world of proteins and peptides.

At its core, capillary electrophoresis (CE) is a separation technique that leverages differences in the electrophoretic mobility of charged molecules within a narrow, fused-silica capillary filled with an electrolyte buffer. The fundamental principle involves applying a high voltage across the capillary, causing ions to migrate towards the electrode of opposite charge. The rate of migration, or mobility, is influenced by factors such as the molecule's charge, size, and shape, as well as the properties of the buffer and the capillary wall. This makes CE a highly effective method for achieving a high-resolution technique for the separation of a wide variety of molecules of biological interestCapillary Electrophoresis of Proteins and Peptides - Burgi - 1995.
