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.

Klappentext
With the completion of the human genome, the number of protein-based drug candidates has increased dramatically, along with the need to find methods for producing these proteins on a scale large enough to meet demand without compromising the authenticity of the final product. In Therapeutic Proteins: Methods and Protocols, world-class researchers share their innovative and proven techniques for the production of therapeutic proteins downstream of the discovery stage. The methods use a variety of sources for producing therapeutic proteins, including bacterial and yeast expression systems, and insect and mammalian cells, and then cover the purification of the resulting protein using both state-of-the-art and traditional methods, such as those sourced from plasma. Additional chapters offer methods for the characterization of therapeutic proteins throughout the production process, along with methods and strategies for viral inactivation and protein formulation. The protocols follow the successful Methods in Molecular Biology™ series format, each offering step-by-step laboratory instructions, an introduction outlining the principles behind the technique, lists of the necessary equipment and reagents, and tips on troubleshooting and avoiding known pitfalls.
Authoritative and highly practical, Therapeutic Proteins: Methods and Protocols offers both novice and experienced researchers the latest innovative, readily reproducible techniques, as well as helpful commentaries on the development and production of therapeutic proteins, ranging from their expression to actual formulation.
