Effective electrophoretic mobilities and charges of anti-VEGF proteins determined by capillary zone electrophoresis

Determination of absolute mobilities, pK values and separation numbers by capillary zone electrophoresis: effective mobility as a parameter for screening

Migration times or apparent mobilities can never be used for the identification of ionic species in capillary zone electrophoresis if an electroosmotic flow (EOF) is present, because the velocity of this flow varies considerably with the “state” of the capillary. From the migration times of the EOF and the ionic species, the effective mobilities can be calculated. These effective mobilities are...

Study of the Electrophoretic Behavior of Cephalosporins by Capillary Zone Electrophoresis.

PURPOSE The aim of the study was the characterization of the electrophoretic behavior of cephalosporins from different generation having different structural characteristics in order to develop a rapid, simple and efficient capillary electrophoretic method for their identification and simultaneous separation from complex mixtures. METHODS Ten cephalosporin derivatives (cefaclor, cefadroxil, c...

Application of the Phenomenological Model to Electrophoretic Mobility in Mixed Solvent Electrolyte Systems in Capillary Zone Electrophoresis

The phenomenological model of Khossravi and Connors (1992) has been adopted to calculate the electrophoretic mobility of drugs at different concentrations of solvents in a binary mixture. The accuracy and predictability of the model have been evaluated employing 14 experimental data sets by using average percentage mean deviation (APMD). The obtained APMD for correlative and predictive studies ...
