AN IMPROVED METHOD FOR THE CAPILLARY ELECTROPHORESIS OF NUCLEIC ACIDS, PROTEINS AND LOW MOLECULAR CHARGED COMPOUNDS

摘要

A method of capillary electrophoresis utilizing a capillary tube made up of hydrophobic plastics, characterized in that the inner surface of said capillary is coated with a hydrophilic polymer comprising a polyhydroxy polymer exhibiting groups - B - R, where R is a hydrocarbyl group and B is a bridge binding to the polyhydroxy polymer, preferably by substituting a hydrogen in a hydroxy group of the polyhydroxy polymer.
