Development and Optimization of Novel Short Layer Monolithic Supports for cGMP Production of Plasmid DNA

By using a combination of two CIM® tube monolithic columns, OH and DEAE chemistry, we were able to successfully purify plasmid DNA from bacterial culture without using RNase. Purified plasmid DNA is very pure, since common contaminants, such as proteins, genomic DNA, endotoxins and RNA were under the detection limit. The scale up units produced according to cGMP standard are already used for the purification of plasmid DNA for gene therapy purposes on industrial scale.
