Abstract
With the advent of nucleic acid silencing technologies and the need for high purity diagnostic and therapeutic oligonucleotides, there is a need for high-capacity chromatographic supports that can deliver economic purification processes. A new, 30 micron, mono-sized, polymeric resin has been recently developed that provides high resolution and high capacity for synthetic oligonucleotides. Physical properties of this new resin will be described, including particle size uniformity, ion exchange capacity, pressure stability, and chemical stability. The purification of two synthetic 12mer DNA oligonucleotides (AAA CCT GAT GTG and GGT GGT GGT GGT) will be demonstrated, and will compare yields and purities to those from commercially available anion exchange resins.
