Principles and practice of peptide analysis with capillary zone electrophoresis.
Capillary electrophoresis provides a new analytical tool that complements reversed-phase high-performance liquid chromatography separations of peptides. The principles of this technique and their application to developing peptide analyses are described. Detailed recipes for useful buffers and for preparation of the instrument are provided. A sequence of generally useful experiments is suggested...
متن کاملAnalysis of ion-association equilibrium of precipitable dipicrylaminate ion in aqueous solution by capillary zone electrophoresis.
The ion-association equilibrium of the dipicrylaminate ion (DPA(-)) was investigated in an aqueous solution with alkali metal ions and with its 18-crown-6 ether complexes as pairing cations by capillary zone electrophoresis (CZE). Although DPA(-) is precipitable with the pairing cations of K(+) and Cs(+) in a homogenous aqueous solution, a low concentration of DPA(-) below its solubility suppre...
متن کاملHUMIC SUBSTANCES Capillary Zone Electrophoresis
Humic substances (HS) which are widespread in the soil, present structural complexity and polyelectrolyte properties. Many techniques and methods have been used to obtain more information about them, as reviewed by Davies and Ghabbour in 1999. The characterization of HS has been the focus of intense research for many years because the organic matter in soil contributes to the quality of the soi...
متن کاملAnalysis of ion-association reaction in aqueous solution and its utilization by capillary zone electrophoresis.
Electrophoretic migration of analytes in capillary zone electrophoresis (CZE) reflects the dissolved status of analytes in solution, and the electrophoretic mobility is controlled to develop the resolution among analytes by adding a "modifier" to the migrating solution. Such addition of modifier is essentially the utilization of molecular interactions. Precise measurement of electrophoretic mob...
