Quantitation and purification of polymerase chain reaction products by high-performance liquid chromatography

This work describes the application of the fully automated high-performance liquid chromatographic system to the analysis of PCR-amplified products. Efficient separations of both DNA restriction fragments and PCR products were performed using an anion-exchange DEAE-NPR column, packed with 2.5-microns nonporous particles. The automated HPLC method was employed for the separation, quantitation, and purification of PCR products in less than 10 min in a single step.
