摘要:

Polysaccharide with molecular weight of 100KD was oxidized by periodic acid and covalently bound onto the surface of capillary. The electroosmotic flow of the coated capillary decreased at pH 4-8. Basic proteins can be separated by high-performance electrophoresis with the coated capillary with good reproducibility.
