Glyco Engineering

Conceived with the intention of providing an array of strategies and technologies currently in use for glyco-engineering distinct living organisms, this book contains a wide range of methods being developed to control the composition of carbohydrates and the properties of proteins through manipulations on the production host rather than in the protein itself. The first five sections deal with host-specific glyco-engineering and contain chapters that provide protocols for modifications of the glycosylation pathway in bacteria, yeast, insect, plants and mammalian cells, while the last two sections explore alternative approaches to host glyco-engineering and selected protocols for the analysis of the N-glycans and glyco-profiling by mass spectrometry. Written for the highly successful Methods in Molecular Biology series, 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. Authoritative and extensive, Glyco-Engineering: Methods and Protocols offers vast options to help researchers to choose the expression system and approach that best suits their intended protein research or applications.

Sugar chains (glycans) are often attached to proteins and lipids and have multiple roles in the organization and function of all organisms. "Essentials of Glycobiology" describes their biogenesis and function and offers a useful gateway to the understanding of glycans.

Glyco-engineering is being developed as a method to control the composition of carbohydrates and to enhance the pharmacological properties of monoclonal antibodies (mAbs) and other proteins. In Glycosylation Engineering of Biopharmaceuticals: Methods and Protocols, experts in the field provide readers with production and characterization protocols of glycoproteins and glyco-engineered biopharmaceuticals with a focus on mAbs. The volume is divided in four complementary parts dealing with glyco-engineering of therapeutic proteins, glycoanalytics, glycoprotein complexes characterization, and PK/PD assays for therapeutic antibodies. Written in the highly successful Methods in Molecular BiologyTM 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. Authoritative and cutting-edge, Glycosylation Engineering of Biopharmaceuticals: Methods and Protocols serves as an ideal guide for scientists striving to push forward the exciting field of engineered biopharmaceuticals.

Glycans have long been known to be one of the most abundant biological molecules in living organisms. They can function as energy compounds, form structural cell wall/matrix polymers, or exist as oligomers that are attached on proteins, lipids and natural products to influence their properties and function. Because of their important biological roles, glycans have great potential for applications in the development of new drugs, materials, food additives and many other products. However, it is often difficult to directly obtain glycans from natural sources with ideal properties for these applications. Thus, modification of glycan structures for desired properties has emerged as an active area of research. This research area is generally called glycoengineering.

This book reviews the latest trends in glycobiotechnology, it offers an authoritative discussion about future directions of glycoengineering, and it provides a comprehensive overview about the current and emerging approaches to identify, quantify and characterize glycosylated proteins. Divided into 14 chapters, the book outlines recombinant glycoprotein expression in mammalian cells, insect cells, yeast, and bacterial systems. It covers the chemical and enzymatic syntheses of glycans and glyconjugates, and addresses the impact of glycosylation on protein function for the development of biologicals including vaccines. In the final chapters of the book, readers will discover more about the state-of-the-art in glycomics, glycoproteomics and glycan array technologies.

The field of antibody engineering has become a vital and integral part of making new, improved next generation therapeutic monoclonal antibodies, of which there are currently more than 300 in clinical trials across several therapeutic areas. Therapeutic antibody engineering examines all aspects of engineering monoclonal antibodies and analyses the effect that various genetic engineering approaches will have on future candidates. Chapters in the first part of the book provide an introduction to monoclonal antibodies, their discovery and development and the fundamental technologies used in their production. Following chapters cover a number of specific issues relating to different aspects of antibody engineering, including variable chain engineering, targets and mechanisms of action, classes of antibody and the use of antibody fragments, among many other topics. The last part of the book examines development issues, the interaction of human IgGs with non-human systems, and cell line development, before a conclusion looking at future issues affecting the field of therapeutic antibody engineering. Goes beyond the standard engineering issues covered by most books and delves into structure-function relationships Integration of knowledge across all areas of antibody engineering, development, and marketing Discusses how current and future genetic engineering of cell lines will pave the way for much higher productivity

A new focus on glycoscience, a field that explores the structures and functions of sugars, promises great advances in areas as diverse as medicine, energy generation, and materials science, this report finds. Glycans-also known as carbohydrates, saccharides, or simply as sugars-play central roles in many biological processes and have properties useful in an array of applications. However, glycans have received little attention from the research community due to a lack of tools to probe their often complex structures and properties. Transforming Glycoscience: A Roadmap for the Future presents a roadmap for transforming glycoscience from a field dominated by specialists to a widely studied and integrated discipline, which could lead to a more complete understanding of glycans and help solve key challenges in diverse fields.
