  • Process for preparing polynucleotides on a solid support in a tightly packed bed
    Patent number: 5869643
    Abstract: The present invention relates to a process for preparing polynucleotides on a solid support in a reactor in the form of a column through which solutions of reagents and/or solvents are circulated, wherein the solid phase constituting said solid support is immobilized in said reactor, and said solutions migrate in the column and through the solid phase according to a frontal progression, such that the successive solutions from each step of a synthesis cycle do not mix at all, or very little.The subject of the present invention is also a reactor consisting of a column completely filled with particles of porous materials constituting the solid support, and a synthesis device including such a reactor.
