Over the past decade, the transient gene expression (TGE) technology platform has been actively pursued to produce a wide range of therapeutic proteins, monoclonal antibodies, and vaccines for mainly preclinical assessment, due to its short development times and low overall cost. This book updates the latest advances in the field, with focusing on systematic description of the technology from cell lines, cell culture conditions, vector construction, expression strategy, current protocols, optimisation of the procedure, and potential for clinical application. As a conclusion, the author foresees that therapeutic biopharmaceutics will be manufactured for clinical development using TGE technology in the near future because of its fast development time, good protein expression, acceptable quality of product and due to the progress which has been made in analytical methodology and process quality control. The objectives of this book are to summarise current TGE protocols, to describe optimisation of the technology through the latest advances, and to explore clinical applications of the technology. It gives the reader a good insight into the latest development and future application of the technology platform, including: The current protocols from small to large scale for different cells. Optimisation methods in construction designing, transfection procedures, and cell culture conditions. Overall quality of the product from the transient gene expression. Future clinical application of the technology platform.

With the recent completion of the sequencing of the human genome, it is widely anticipated that the number of potential new protein drugs and targets will escalate at an even greater rate than that observed in recent years. However, identification of a potential target is only part of the process in developing these new next generation protein-based “drugs” that are increasingly being used to treat human disease. Once a potential protein drug has been identified, the next rate-limiting step on the road to development is the production of sufficient authentic material for testing, charact- ization, clinical trials, and so on. If a protein drug does actually make it through this lengthy and costly process, methodology that allows the production of the protein on a scale large enough to meet demand must be implemented. Furthermore, large-scale production must not compromise the authenticity of the final product. It is also nec- sary to have robust methods for the purification, characterization, viral inactivation and continued testing of the authenticity of the final protein product and to be able to formulate it in a manner that retains both its biological activity and lends itself to easy administration. Therapeutic Proteins: Methods and Protocols covers all aspects of protein drug production downstream of the discovery stage. This volume contains contributions from leaders in the field of therapeutic protein expression, purification, characterization, f- mulation, and viral inactivation.

Recombinant Proteins from Plants is one of the most exciting and fastest developing areas in biology. The latest molecular techniques are being applied to the exploitation of plants as novel expression systems for the p- duction and overproduction of heterologous and native proteins. Transgenic plant technology is currently used in three broad areas: the expression of - combinant proteins to improve crop quality by increasing disease/pest res- tance or increasing tolerance to stress, optimizing plant productivity and yield by the genetic manipulation of metabolic pathways, and the large-scale co- effective production of recombinant proteins for use as specialist industrial or therapeutic biomolecules. The intention of Recombinant Proteins from Plants is to provide c- prehensive and detailed protocols covering all the latest molecular approaches. Because the production oftransgenic plants has become routine in many la- ratories, coverage is also given to some of the more "classical" approaches to the separation, analysis, and characterization of recombinant proteins. The book also includes areas of research that we believe will become increasingly important in the near future: efficient transformation of monocots with Agrobacterium optimizing the stability of recombinant proteins, and a section highlighting the immunotherapeutic potential of plant-expressed proteins.
Fundamentals of Recombinant Protein Production, Purification and Characterization is organized into nine chapters in a logical fashion that cover an introduction to recombinant proteins and expression in different host expression systems, extraction, purification and analysis of proteins. This important reference features protocols, along with the advantages and disadvantage of each expression hosts and characterization technique (presented in tabular format) and offers detailed coverage of all aspects of protein production and processing (upstream and downstream processing) in one place. Finally, the book ends with different characterization techniques. Production of recombinant proteins for biotechnological and therapeutic applications at a large scale is an essential need of mankind. With the huge application potential of therapeutic and industrial proteins, there has been increasing demand for effective and efficient bioprocessing strategies. Recent progress around recombinant DNA technologies and bioprocessing strategies has paved the way for efficient production of recombinant proteins. Important factors such as insolubility and cost of production need to be considered for large scale production of these recombinant proteins. Includes step-by-step reproducible protocols while also providing updated information on the rationale and latest developments in expression systems Can also be used as a handbook for protein expression and purification as expression systems and chromatographic methods are explained in detail Consists of notes on troubleshooting from the eminent researchers in the field Provides comprehensive information on protein production, purification and characterization in a single volume Describes different purification methods for comparatively difficult to obtain proteins Brings the topics of recombinant protein expression, purification and characterization together, thereby making it the first resource on how to solve problems with respect to upstream and downstream processing of heterologous proteins
