A simple and rapid method for purification of oligodeoxyribonucleoside methylphosphonates.
An alternative dimethoxytrityl-on (dmt-on) method is described to purify hydrophobic oligodeoxyribonucleoside methyl-phosphonates (OM) with a phosphodiester linkage at the 5' end, instead of the conventional dmt-off method using a DEAE ion-exchange column. This method is modified from the reverse-phase method for purification of normal oligonucleotides.
