ABSTRACT:
The present invention provides for polycationic buffers for the gel electrophoresis of and methods for obtaining improved separation and resolution of nucleic acids. In particular, the invention provides for a buffer consisting essentially of histidine for the gel electrophoresis of oligonucleotides ranging from a few to about 70 nucleotides in length. Polycationic buffers may be used for both analytical and preparative purposes and result in a nearly two-fold improvement in both separation and resolution of the nucleic acid bands. Furthermore, the use of polycationic buffers reduces the electrophoresis time by a factor of about three due to the low conductivity of the buffers.
