This book opens with a description of fundamental aspects of protein adsorption to surfaces, a phenomenon that plays a key role in biotechnological applications, especially at solid-liquid interfaces. Presented here are methods for studying adsorption kinetics and conformational changes such as optical waveguide lightmode spectroscopy (OWLS). Also described are sensitive bench techniques for measuring the orientation and structure of proteins at solid-liquid interfaces, including total internal reflection ellipsometry (TIRE), dual polarisation interferometry (DPI) and time of flight - secondary ion mass spectrometry (TOF–SIMS). A model study of fibronectin at polymer surfaces is included, as are studies using microporous membranes and textiles with immobilized enzymes for large-scale applications. Biocompatibility, anti-fouling properties and surface modification to modulate the adsorption and activity of biomolecules are among the other topics addressed in this invaluable book.

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.

Fluid interfaces are promising candidates for confining different types of materials, e.g., polymers, surfactants, colloids, and even small molecules, to be used in designing new functional materials with reduced dimensionality. The development of such materials requires a deepening of the physicochemical bases underlying the formation of layers at fluid interfaces as well as on the characterization of their structures and properties. This is of particular importance because the constraints associated with the assembly of materials at the interface lead to the emergence of equilibrium and features of dynamics in the interfacial systems, which are far removed from those conventionally found in traditional materials. This Special Issue is devoted to studies on the fundamental and applied aspects of fluid interfaces, and attempts to provide a comprehensive perspective on the current status of the research field.

Albumin Structure, Function and Uses reviews the many facets of serum albumin, including its history and evolutionary development, structure and function, synthesis, degradation, distribution and transport, and metabolic behavior. The use, misuse, and abuse of albumin in the treatment of disease are also discussed. This book is comprised of 17 chapters and begins with a commentary on how albumin is used, misused, and abused in the treatment of disease such as peptic ulcer, and a description of the real indications for its use. Concepts in albumin purification are then examined, along with the amino acid sequence of serum albumin and some aspects of its structure and conformational properties. Subsequent chapters explore the phylogenetics of albumin; albumin binding sites; clinical implications of drug-albumin interaction; genetics of human serum albumin; and hepatic synthesis of export proteins. Albumin catabolism and intracellular transport are also considered, together with surgical and clinical aspects of albumin metabolism. This monograph should be a useful resource for biochemists and clinicians.

This volume explores experimental and computational approaches to measuring the most widely studied protein assemblies, including condensed liquid phases, aggregates, and crystals. The chapters in this book are organized into three parts: Part One looks at the techniques used to measure protein-protein interactions and equilibrium protein phases in dilute and concentrated protein solutions; Part Two describes methods to measure kinetics of aggregation and to characterize the assembled state; and Part Three details several different computational approaches that are currently used to help researchers understand protein self-assembly. Written in the highly successful Methods in Molecular Biology series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Thorough and cutting-edge, Protein Self-Assembly: Methods and Protocols is a valuable resource for researchers who are interested in learning more about this developing field.
