Abstract
The filling of an internally coated capillary with a gel in its polymerized state without damaging the gel. The coating prevents bonding of the gel to the inside of the capillary. The gel comprises up to 6% acrylamide and 0-5% crosslinker. The gel can be advantageously and conveniently used in automated electrophoresis systems for automatic replacement of spent gel.
