  • Improved process for the purfication of synthetic oligonucleotides
    Patent number: 4997927
    Abstract: A process for the purfication of synthetic oligonucleotides is described which drastically simplifies the hitherto very time consuming purification process. The deprotection solution is adsorbed without being concentrated on a carrier having reversed phase properties and optionally ion exchanger properties, the oligonuleotides without lipophilic protecting group are removed, their protecting group is cleaved off from the adsorbed oligonucleotides, the adsorbed oligonucleotides are washed and eluted from the carrier and then purified in a manner known per se.
