title: The purification of oligodeoxyribonucleotides with a high guanosine content by anion exchange HPLC.
abstract: Anion exchange HPLC purification of synthetic oligonucleotides with a high guanosine content is difficult. This study has demonstrated that these sequences can be successfully purified by anion exchange HPLC using standard conditions provided that the base protecting groups (isobutyryl[ib] and benzoyl[bz]) are retained on the otherwise deprotected oligomer.
