A Novel Plasmid DNA Purification Process: From Laboratory to Production Scale

Application of plasmid DNA for gene therapy and vaccination has gained substantial interest in the last two decades. Topological homogeneity and impurity content are crucial for therapeutic usage of pDNA. Downstream processing has major influence on achieving regulatory demands in pDNA production and in order to get optimal purity different purification techniques have to be applied. It was demonstrated that methacrylate monoliths can be used for efficient purification process of plasmid DNA. High dynamic binding capacities and high flow rates of methacrylate monolith enable excellent purity and productivity.
