Dna separation using linear polymer solutions with dimethyl sulfoxide

摘要

The invention is directed to a high throughput nucleic acid separation method using an improved uncrosslinked polymer separation matrix for increasing read length and separation speed, while maintaining accuracy, for, e.g., nucleic acid sequencing. The separation matrix of the invention includes a denaturant comprising dimethyl sulfoxide (DMSO). Preferably, the separation matrix may further comprise urea. Preferred matrix polymers include linear polyacrylamide, poly(ethylene oxide), hydroxyethyl cellulose, poly(dimethylacrylamide) and poly(vinylpyrrolidone).
