Capillary zone electrophoresis (CZE) was applied to the analysis of a recently described class of synthetic branched peptides, multiple antigen peptides (MAPs). In comparison with high-performance liquid chromatography (HPLC), CZE showed superior resolution of minor impurities in samples of MAPs obtained by preparative chromatography. MAPs that differed only in the substitution of uncharged residues (Ala-Ser) could be separated by the addition of organic solvents (acetonitrile, methanol, ethanol) to the aqueous background electrolyte.

Abstract
Capillary zone electrophoresis (CZE) was applied to the analysis of a recently described class of synthetic branched peptides, multiple antigen peptides (MAPs). In comparison with high-performance liquid chromatography (HPLC), CZE showed superior resolution of minor impurities in samples of MAPs obtained by preparative chromatography. MAPs that differed only in the substitution of uncharged residues (Ala-Ser) could be separated by the addition of organic solvents (acetonitrile, methanol, ethanol) to the aqueous background electrolyte.File in questo prodotto:
