Process for separation of oligonucleotide of interest from a mixture

摘要

A method for separation of an oligonucleotide from a mixture using a biphasic mobile phase / stationary phase liquid - liquid chromatography system. A first mobile phase contains the oligonucleotide and the stationary phase contains an exchanger substance that removably binds to the target oligonucleotide. The mobile phase is caused to flow in contact with the stationary phase in a liquid - liquid chromatography apparatus such that the oligonucleotide becomes bound to the exchanger substance in the liquid stationary phase. The oligonucleotide is then displaced from the liquid stationary phase into a second liquid mobile phase by means of a displacer substance able to displace the oligonucleotide from the stationary phase into the second mobile phase.
