Proteins at Liquid Interfaces


Book Description

The interfacial behaviour of surfactants and proteins, and their mixtures, is of importance in a wide range of areas such as food technology, detergency, cosmetics, coating processes, biomedicine, pharmacy and biotechnology. Methods such as surface and interfacial tension measurements and interfacial dilation and shear rheology characterise the relationships between these interfacial properties and the complex behaviour of foams and emulsions is established. Recently-developed experimental techniques, such as FRAP which enable the measurement of molecular mobility in adsorption layers, are covered in this volume. The development of theories to describe the thermodynamic surface state or the exchange of matter for proteins and protein/surfactant mixtures is also described. Features of this book: • Reflects the state-of-the-art research and application of protein interfacial layers rather than a snapshot of only some recent developments. • Emphasis is placed on experimental details as well as recent theoretical developments. • New experimental techniques applied to protein interfacial layers are described, such as FRAP or ADSA, or rheological methods to determine the mechanical behaviour of protein-modified interfaces. • A large number of practical applications, ranging from emulsions relevant in food technology for medical problems such as lung surfactants, to the characterisation of foams intrinsic to beer and champagne production. The book will be of interest to research and university institutes dedicated to interfacial studies in chemistry, biology, pharmacy, medicine and food engineering. Industrial departments for research and technology in food industry, pharmacy, medicine and brewery research will also find this volume of value.







Protein Instability at Interfaces During Drug Product Development


Book Description

Proteins are exposed to various interfacial stresses during drug product development. They are subjected to air-liquid, liquid-solid, and, sometimes, liquid-liquid interfaces throughout the development cycle-from manufacturing of drug substances to storage and drug delivery. Unlike small molecule drugs, proteins are typically unstable at interfaces where, on adsorption, they often denature and form aggregates, resulting in loss of efficacy and potential immunogenicity. This book covers both the fundamental aspects of proteins at interfaces and the quantification of interfacial behaviors of proteins. Importantly, this book introduces the industrial aspects of protein instabilities at interfaces, including the processes that introduce new interfaces, evaluation of interfacial instabilities, and mitigation strategies. The audience that this book targets encompasses scientists in the pharmaceutical and biotech industry, as well as faculty and students from academia in the surface science, pharmaceutical, and medicinal chemistry areas.




Masters Theses in the Pure and Applied Sciences


Book Description

Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS)* at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dis semination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this jOint undertaking we had concluded that it was in the interest of all concerned if the printing and distribution of the volumes were handled by an international publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Corporation of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 40 (thesis year 1995) a total of 10,746 thesis titles from 19 Canadian and 144 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this impor tant annual reference work. While Volume 40 reports theses submitted in 1995, on occasion, certain uni versities do report theses submitted in previous years but not reported at the time.




Food Proteins and Their Applications


Book Description

Reviews the physiochemical properties of the main food proteins and explores the interdependency between the structure-function relationship of specific protein classes and the processing technologies applied to given foods. The book offers solutions to current problems related to the complexity of food composition, preparation and storage, and includes such topics as foams, emulsions, gelation by macromolecules, hydrolysis, microparticles/fat replacers, protein-based edible films, and extraction procedures.

Therapeutic Monoclonal Antibodies: From Lot Release to Stability Testing


Book Description

Therapeutic Monoclonal Antibodies: From Lot Release to Stability Testing is a highly topical resource on a subject of interest for scientists and researchers working on monoclonal antibodies' characterization, release testing, stability testing and similarity assessments of monoclonal antibodies in the biopharmaceutical industry. Monoclonal antibodies (mAbs) are large, extremely complex and dynamic biomolecules, so it can be challenging to develop well-characterized therapeutic antibodies that meet regulatory expectations that are also in-line with commercialized standards for different drug markets. Lot release testing and understanding the stability of the mAb over a period of time, and in different environmental conditions, is an indispensable aspect of mAb physicochemical characterization. This book covers the process, including extensive analysis that starts with quantifying the purity attribute to glycan profiling and identifying the mAb primary structure. The book has a primary purpose of focusing on both Lot release testing and stability testing of monoclonal antibodies (subjects not covered in any great detail in other books). Discusses, in detail, the Lot release methods for both drug substance and drug product, along with their importance in process sample analysis Gives specific attention to general characteristics tests, such as pH determination, osmolality, sub-visible particle count, appearance and visible tests, and regulatory/pharmacopeial guidelines Includes different kinds of stability testing (real time, accelerated and stressed) and their importance and determinations on product shelf life Presents regulatory guidelines on ICH Q2R1, ICHQ6B and ICHQ5C, which are discussed along with analytical method validation, monoclonal antibodies physicochemical characterization and stability testing Provides different characterization methods and validation and development case studies of monoclonal antibodies, including biosimilars and innovators
