title: Coated capillaries and additives for the separation of proteins by capillary zone electrophoresis and capillary isoelectric focusing.
abstract: Strategies reported for the separation of proteins in capillary zone electrophoresis and capillary isoelectric focusing are reviewed. The strategies are grouped into two categories: coated capillaries and buffer/sample additives. Success attained with each case and also, more importantly, the limitations of the methodology are discussed. Recent results from our own laboratory in the area of capillary isoelectric focusing in uncoated, fused silica capillaries using additives are summarized. The advantages and disadvantages of coated columns vs. additives are delineated.
