title: Separation science is the key to successful biopharmaceuticals.
abstract: The impact of economic change, advances in science, therapy and production processes resulted in considerable growth in the area of biopharmaceuticals. Progress in selection of microorganisms and improvements in cell culture and bioreactors is evidenced by increased yields of the desired products in the complex fermentation mixture. At this stage the downstream process of extraction and purification of the desired biopharmaceutical requires considerable attention in the design and operation of the units used for preparative chromatography. Understanding of the process, optimization of column design and experimental conditions have become critical to the biopharmaceutical industry in order to minimize production costs while satisfying new regulatory requirements. Optimization of the purification of biopharmaceuticals by preparative liquid chromatography including an examination of column preparation and bed properties is the focus of this manuscript.
