Abstract
Analytical tube and slab gel electrophoresis has frequently been used to monitor protein purification procedures. the ABI Model 230A HPECTM micropreparative electrophoresis system was used to separate carbonic anhydrase and fractions were analyzed for purity using the ABI Model 270A CE system and compared to silver stained slab gels. Capillary electrophoresis provides a simple, rapid method for the analysis of protein samples.
