Abstract
The present disclosure discusses a method of separating and/or purifying polynucleotides. The method includes injecting a sample into a chromatographic column that is packed with a porous sorbent having a pore size that substantially excludes the polynucleotides from the sorbent. This restricted access to the sorbent allows separation of large polynucleotides from each other and from smaller molecular weight impurities.
