Abstract
Although electrophoresis is one of the basic methods of the modern
molecular biology laboratory, new ideas are being suggested at an
accelerated rate, in large part because of the pressing demands of
the biomedical community. Although we now have, at least for some
methods, a fairly good theoretical understanding of the physical
mechanisms that lead to the observed peak spacings, widths and shapes,
this knowledge is often too qualitative to be used to guide further
technical developments and improvements. In this article, we review
some selected elements of the current state of our theoretical ignorance,
focusing mostly on DNA electrophoresis, and we offer several suggestions
for further theoretical investigations.
