Application of plasmid DNA for gene therapy and vaccination has gained huge interest in last two decades. Topological homogeneity and impurity content are crucial for therapeutic usage of pDNA. Major influence on achieving regulatory demands in pDNA production has downstream processing and in order to get optimal purity different purification techniques have to be included. 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 enabled excelent purity and productivity.
