Upon publication of the first edition of "Therapeutic Peptides and Proteins" ten years ago, there were only 19 biotechology medicines on the market. Currently, there are more than 100, with at least 400 more in various stages of development. That alone would be grounds for a new edition. Add to that the fact that it is still difficult to find up-to-date, relevant information on protein formulation and/or delivery systems and the need for a new edition is self-evident. This second edition continues the tradition of providing a ready-to-use reference of accurate information, tables, and illustrations. The book begins with the basics of the origin of recombinant proteins, explores structural and analytical aspects, and moves on to discuss the stability of proteins and peptides. Against this background, the author addresses preformulation and formulation considerations and provides detailed information on important topics such as lyophilization. He goes on to discuss various delivery systems, including controlled release delivery systems and products currently on the market. The book also contains newly added regulatory information and thoroughly investigates therapeutic drugs made from proteins as well as protein-based vaccines. A new chapter on recombinant protein subunit vaccines and their delivery systems has been added. The work of a single author, the book provides complex information in a simple, elegant, and cohesive style. The author minimizes overlap between coverage and includes extensive cross-referencing that links related topics. Completely revised and updated, packed with cutting-edge information, the second edition once again fills the need for a reference that pulls all the relevant information together into one resource.
