| 摘要 |
<p>The present invention relates to a capillary tube for electrophoresis, the capillary tube having an inner surface and an outer surface, at least a portion of the inner surface coated with a first polymer layer, the first polymer layer comprising a plurality of polymer groups, each polymer group comprising a polymer of the formula (CH 2 CH 2 NH) x which is attached by a linker group of the formula -(CH 2 ) n -N-R 3 to an anchor group, the anchor group being covalently bonded to the inner surface of the capillary, where two or more than two polymer groups are covalently bonded to each other by a cross-linker, and where X is an integer greater than 5, R 3 is selected from the group consisting of hydrogen, alkyl groups, and (CH 2 CH 2 NH) z where z is an integer between 1 and 15.</p> |
