Workshop Write Up

Workshop Overview

Proteomics Facility, School of Life Sciences, University of Hyderabad (UoH) along with GE Fast Trak Training & Education, Bangalore (GE Healthcare Life Sciences) jointly invites you to a technology workshop on Large Scale Protein Purification Systems – a unique platform that showcases latest developments in downstream techniques with ÄKTA pilot and FlexStand Benchtop pilot systems. The 3-day workshop at UoH provides an exceptional hands-on learning experience for process development and manufacturing scientists, faculty, students, engineers, plant operators, and support staffs. During the three-day session, we will walk you through solutions which can enable you to intensify your downstream process. The three-day basic practical course covers downstream processing techniques suitable for production-scale protein purification and illustrates how these techniques should be considered for process development.

The focus of this course is on the understanding of the techniques and the parameters governing separation. Detailed presentations of the downstream processing techniques used (crossflow filtration & chromatography) are included as well as lectures covering column packing, purification strategies, column maintenance and process hygiene are briefly presented to describe the industrial environment and its principal objectives. During the practical session, you will work in small groups and use ÄKTA pilot and Flex stand filtration systems to perform the experiments.

Title of the talk: "Large-Scale Purification of Recombinant Proteins: Current Status and Future Trends"

There is an ever-increasing requirement for protein production in industrial and academic settings for a variety of applications. These include exploratory research, drug discovery initiatives, biopharmaceutical production, target validation, and high-throughput screening. With the advent of modern fermentation technologies have resulted in the production of increased yields of proteins of economic, biopharmaceutical, and medicinal importance. Consequently, there is an absolute requirement for the development of rapid, cost-effective methodologies which facilitate the purification of such products. A comprehensive overview of a selection of key purification methodologies currently being applied in both academic and industrial settings will be presented. Also discussed will be how innovative and effective protocols such as aqueous two-phase partitioning, membrane chromatography, field-assisted and electrophoretic separation methods, and high-performance tangential flow filtration may be applied independently of or in conjunction with more traditional protocols for downstream processing applications. The use of combinatorial chemistry and phage-display technologies is generating a large repertoire of ligands specific for virtually any protein. It is likely that these ligands will be increasingly used in future affinity chromatographic applications for large-scale recombinant protein purification.

Title of the talk: “Purification in Industry”.

Separation techniques are very essential in achieving biochemical understanding of biological/physiological phenomena/processes. Reductionist biology believes in analyzing complex systems by first breaking it into simpler systems and analyzing one at a time the simpler system. If a physiological process is mediated by ‘n’ number of enzymes/macromolecules, biochemists believe that each of the enzymes/macromolecules should be separated from others and studied in vitro before understanding the whole process. This necessitates the use of appropriate separation techniques. Obtaining a given enzyme/macromolecule, free from the others, in a homogeneous state is termed ‘purification’. Physical separation techniques like filtration, decantation, evaporation etc. only result in separating states of matter from each other i.e. solid from liquid, liquid from gas etc. Separation techniques to achieve separation of components of a molecular mixture (usually solid in solvent i.e. solutions) are based on exploitation of differences in physical properties (like charge density, solubility in water, size etc.) of the components of the mixture to achieve separation. For example, proteins differ from each other in either size (molecular mass), isoelectric point, net charge at a given pH of the solution, affinity to a small ligand or solubility in a salt solution. Precipitation (phase separation), chromatography, electrophoresis, differential adsorption etc. are some techniques used to achieve separation, exploiting the differences in the above mentioned physico-chemical properties of macromolecular components of a mixture. Biochemists therefore, use separation techniques most of their time. When these techniques are used in laboratory scale, for separating small quantities of biomolecules, they are usually called analytical techniques. On the other hand, if applied to large quantities (grams to kilograms) of biomolecular separations (i.e. industrial scale) they are termed as ‘downstream processes’. Separation techniques are applicable not only for the purification of functional proteins in native state from their natural sources (i.e. a tissue of plant or animal origin or from microbial source) but also recombinant proteins made in a large biomass, from either culture medium or cells that are artificially grown in fermenters and reactors. Biotech industries make large quantities of enzymes, hormones, vaccines, antibodies and many other functional proteins and peptides. Many of them are based on using rDNA techniques and are usually expressed in bacterial, insect, mammalian and plant cells in culture or even in intact animals and plants. The latter are designated transgenic animals or plants. The expressed recombinant protein becomes a biopharmaceutical only when purified from the source in homogeneous state and proven to possess biological activity at a given level of potency. Downstream processing involves judicious use of novel separation techniques like salt precipitations, ion-exchange chromatography, gel permeation chromatography, smart polymer based phase separations, membrane based separations, pseudo-affinity chromatography employing immobilized affinity ligands like textile dyes or even immobilized antibodies, differential adsorption and desorption etc. There are hundreds of chromatography materials or gels, affinity ligands etc. One has to understand the theory underlying the separation efficiency including yield. Hence the specific activity (in defined units/mg) of the final product is an important indicator of separation efficiency. Bioassays in vitro/in vivo are essential components of any purification strategy.
