Use of ethanolamine for sample stacking in capillary electrophoresis

Electrophoresis. 1998 Oct;19(14):2440-4. doi: 10.1002/elps.1150191414.

Abstract

Capillary zone electrophoresis (CZE) in the presence of ethanolamine was used in a micropreparative mode. Sample volumes up to 1 microL could be loaded onto a 100 microns diameter capillary without loss in resolution. Coupled to narrow-bore reversed-phase high-performance liquid chromatography, ethanolamine-CZE allowed the collection of sufficient amounts of pure peptidic material to perform amino acid sequence analysis.
