Oligonucleotide analysis by anion exchange HPLC.
The ability to resolve and purify synthetic oligonucleotides by high performance anion exchange chromatography was evaluated using two wide pore polymeric HPLC matrices. The materials used are rigid macroporous copolymers which have a fully quaternised polyethyleneimine coating to provide a strong anion exchange, quaternary amine, functionality. Oligomers of poly(rA), poly(rC) and RNA produced by alkaline hydrolysis of the polymers were chromatographed to evaluate the selectivity of the system prior to the analysis of synthetic oligonucleotides produced using a commercial oligonucleotide synthesizer.
