ABSTRACT:
A series of low molarity conductive media based on non-buffering univalent cations, such as sodium chloride-sodium acetate (SCA), sodium boric acid (SB), lithium boric acid, and lithium acetate mitigate the “runaway” positive feedback heating loop produced by conventional media containing biological amine buffers and permit improved DNA electrophoresis under the conditions of low salt concentration. These media serve well in ultra-fast DNA electrophoresis and in high-resolution separations of RNA and DNA fragments.
