[Study on the separation of proteins in human serum by high performance capillary zone electrophoresis].

A high performance capillary zone electrophoretic method has been developed for the separation of proteins in human serum. Sera were diluted with a buffer (0.05 mol/L boric acid, pH 8.80), and then introduced hydrodynamically into a 37 cm (32 cm to detector) x 50 microns i.d. fused-silica capillary, electrophoresed for 12 min using a boric buffer solution (0.10 mol/L, pH 9.35; containing 4 g/L of polyethylene glycol 8000), and detected at the wavelength of 200 nm. The method is simple, rapid and repeatable.
