In this paper, we describe a new method for separating LDL and HDL subclasses by nondenaturing polyacrylamide gradient (3-31%) gel electrophoresis, using BioRad Mini Protean II electrophoretic cells. Another low volume but important use of anionic and cationic polyacrylamides is gel electrophoresis for macromolecule separation.
