Much progress has been made in the development of replaceable sieving
polymers and capillary coatings for high-performance DNA sequencing by
capillary electrophoresis. Several studies of parameters that affect
resolution, read length and reproducibility have begun to reveal the p
hysical mechanisms acting on single-stranded DNA during electrophoresi
s through semidilute polymer solutions. Recently developed electro-osm
osis-inhibiting matrix polymers have simplified the process of coating
capillaries, facilitating the automation of high-throughput parallel
systems for large-scale sequencing.
