TL;DR: It has been demonstrated that ToMV, which had been diluted considerably below the sensitivity of ELISA, was concentrated by several orders of magnitude in the one-step procedure, and may provide a much faster and more efficient way to concentrate highly diluted plant viruses.

01 Jan 2005TL;DR: The purpose of this review is to give an overview about short methacrylate monolithic columns commercialised under the trademark Convective Interaction Media (CIM).
Abstract: Modern downstream processing requires fast and highly effective methods to obtain large quantities of highly pure substances. Commonly applied method for this purpose is chromatography. However, its main drawback is its throughput since purification, especially of large molecules, requires long process time. To overcome this problem several new stationary phases were introduced, among which short layer monoliths show superior properties for many applications. The purpose of this review is to give an overview about short methacrylate monolithic columns commercialised under the trademark Convective Interaction Media (CIM). Their unique properties are described from different perspectives, explaining reasons for their application on various areas. Approaches to prepare large volume methacrylate monolithic column are discussed and optimal solutions are given. Different examples of CIM monolithic column implementation are summarised in the last part of the article to give the reader an idea about their advantages.

TL;DR: The efficiency of the monolithic column is demonstrated--where the mass transfer between the stationary and mobile phase is greatly enhanced--for the in-process and final control of the new therapeutics.
Abstract: This review describes the novel chromatography stationary phase - a porous monolithic methacrylate-based polymer - in terms of the design of the columns and some of the features that make these columns attractive for the purification of large biomolecules. We first start with a brief summary of the characteristics of these large molecules (more precisely large proteins like immunoglobulins G and M, plasmid deoxyribonucleic acid (DNA), and viral particles), and a list of some of the problems that were encountered during the development of efficient purification processes. We then briefly describe the structure of the methacrylate-based monolith and emphasize the features which make them more than suitable for dealing with large entities. The highly efficient structure on a small scale can be transferred to a large scale without the need of making column modifications, and the various approaches of how this is accomplished are briefly presented in this paper. This is followed by presenting some of the examples from the bioprocess development schemes, where the implementation of the methacrylate-based monolithic columns has resulted in a very efficient and productive process. Following this, we move back to the analytical scale and demonstrate the efficiency of the monolithic column - where the mass transfer between the stationary and mobile phase is greatly enhanced - for the in-process and final control of the new therapeutics. The combination of an efficient structure and the appropriate hardware results in separations of proteins with residence time less than 0.1 s.

TL;DR: Pressure drop analysis in commercial CIM disk monolithic columns is presented and appears to be a consequence of the monolithic porous structure which is quite different in terms of the pore size distribution and parallel pore nonuniformity compared to the one in conventional packed beds.

TL;DR: This work selected the challenging capture of a VLP from clarified yeast homogenate to examine the performance of this format for bioprocessing and found hydrophobic interaction based separation using a hydroxyl derivatised monolith had the best performance.
