Conjoint Liquid Chromatography Purification of plasmid DNA using CIM Monolithic Supports

Plasmids are excellent genetic vectors and have been widely used in gene manipulation and recombinant DNA technology for a long time. In recent years, plasmids are intensively investigated for gene therapy purposes and genetic vaccination. In this case, plasmid DNA (pDNA) of high purity is required. To follow such demands, several chromatographic steps are commonly needed. In the case of buffer compatibility, columns can be connected in-line to overcome time consuming and yield lowering multiple chromatographic steps. Since each of the unit operations contributes to the dispersion, the resolution is further decreased by each chromatographic step. This drawback might be surmounted by combining several chromatography steps into a single chromatography column. This approach is known as multidimensional or conjoint liquid chromatography (CLC).
