Substrate useful for separating modified oligonucleotides

摘要

Disclosed is a substrate useful for separating unmodified and modified mononucleotides and oligonucleotides. The substrate includes at least 12% polymer in at least 50% (volume:volume) organic solvent, the organic solvent being a denaturing agent. This substrate is easily removable from the capillary using low pressure. Also provided is a method of separating unmodified and modified mononucleotides and oligonucleotides utilizing this substrate.
