Capillary electrophoresis in classical and carrier ampholytes-based background electrolytes applied to separation and characterization of gonadotropin-releasing hormones

► First carrier ampholytes-based capillary electrophoresis (CABCE) of GnRH peptides. ► Superior resolution and faster separations of GnRH peptides by CABCE than by CZE. ► Estimation of effective mobilities and isoelectric points of GnRH peptides by CABCE. ► Theoretical calculation of isoelectric points of GnRH peptides.
