| Research Abstract |
Recently, the use of plasmid DNA as vector for gene therapy or DNA vaccination has become increasingly popular as novel ways of dealing with disease. For such clinical applications, there is a growing need for purification processes to produce pharmaceutical-grade plasmid DNA. In the present study, the application of affinity membrane filtration to plasmid DNA purification and the search of ligand are examined. In addition to the selectivity behaviors in the binding process of plasmid DNA to ligand and the elution process of the bound plasmid DNA, the flux decline behaviors caused by the membrane fouling are also investigated in this system. The agarose gel analysis confirmed usefulness of this method for plasmid DNA purification.
