Monoclonal Antibody Production


Book Description

The American Anti-Vivisection Society (AAVS) petitioned the National Institutes of Health (NIH) on April 23, 1997, to prohibit the use of animals in the production of mAb. On September 18, 1997, NIH declined to prohibit the use of mice in mAb production, stating that "the ascites method of mAb production is scientifically appropriate for some research projects and cannot be replaced." On March 26, 1998, AAVS submitted a second petition, stating that "NIH failed to provide valid scientific reasons for not supporting a proposed ban." The office of the NIH director asked the National Research Council to conduct a study of methods of producing mAb. In response to that request, the Research Council appointed the Committee on Methods of Producing Monoclonal Antibodies, to act on behalf of the Institute for Laboratory Animal Research of the Commission on Life Sciences, to conduct the study. The 11 expert members of the committee had extensive experience in biomedical research, laboratory animal medicine, animal welfare, pain research, and patient advocacy (Appendix B). The committee was asked to determine whether there was a scientific necessity for the mouse ascites method; if so, whether the method caused pain or distress; and, if so, what could be done to minimize the pain or distress. The committee was also asked to comment on available in vitro methods; to suggest what acceptable scientific rationale, if any, there was for using the mouse ascites method; and to identify regulatory requirements for the continued use of the mouse ascites method. The committee held an open data-gathering meeting during which its members summarized data bearing on those questions. A 1-day workshop (Appendix A) was attended by 34 participants, 14 of whom made formal presentations. A second meeting was held to finalize the report. The present report was written on the basis of information in the literature and information presented at the meeting and the workshop.

Therapeutic Antibody Engineering


Book Description

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




Monoclonal Antibodies and Functional Cell Lines


Book Description

This volume serves as a follow-up to our previous book, MonoclonalAntibodies Hybridomas: A New Dimension in Biological Analyses. We continue the theme of monoclonal antibodies and their applications, attempting to cover some of the areas not covered in the previous volume. We again include an appendix de scribing methods useful to those who ar-e beginning to apply these techniques in their own laboratories. This volume will be followed by another concentrating on the combination of monoclonal antibody techniques with molecular genetic techniques to study structure/function relationships at the level of both the gene and gene product.

Naturally Occurring Antibodies (NAbs)


Book Description

This volume illustrates the functional properties of NAbs. Authors from pioneering groups report in their chapters on the tissue homeostatic, tissue regenerating and regulatory properties of NAbs and NAbs in pooled human IgG. Scientists interested in the regulation and modulation of components of the immune system found a whole variety of NAbs to cytokines with regulatory and protective functions and NAbs that modulate, e.g., dendritic cells, regulatory T cells, B cells and granulocytes. Considering the large plasma pools and initial difficulties in preparing IVIG that does not induce adverse effects upon infusion into recipients, this volume ends with a historical chapter on how pooled human plasma was fractionated and the IgG component pretreated for a safe intravenous application.




Cancer Cell Lines Part 1


Book Description

Continuous cell lines derived from human cancers are the most widely used resource in laboratory-based cancer research. The first 3 volumes of this series on Human Cell Culture are devoted to these cancer cell lines. The chapters in these first 3 volumes have a common aim. Their purpose is to address 3 questions of fundamental importance to the relevance of human cancer cell lines as model systems of each type of cancer: 1. Do the cell lines available accurately represent the clinical presentation? 2. Do the cell lines accurately represent the histopathology of the original tumors? 3. Do the cell lines accurately represent the molecular genetics of this type of cancer? The cancer cell lines available are derived, in most cases, from the more aggressive and advanced cancers. There are few cell lines derived from low grade organ-confined cancers. This gap can be filled with conditionally immortalized human cancer cell lines. We do not know why the success rate for establishing cell lines is so low for some types of cancer and so high for others. The histopathology of the tumor of origin and the extent to which the derived cell line retains the differentiated features of that tumor are critical. The concept that a single cell line derived from a tumor at a particular site is representative of tumors at that site is naïve and misleading.




Safety of Biologics Therapy


Book Description

This long overdue title provides a comprehensive, up-to-date, state-of-the art review of approved biologic therapies, with coverage of mechanisms of action, Indications for therapy, immunogenicity and a detailed examination of adverse effects and safety of the many and diverse therapeutic agents presented in a total of 13 chapters. It is predicted that by 2016, biologics will make up half of the world's 20 top-selling drugs and by 2018, biologic medicine sales will account for almost half of the world's 100 biggest selling drugs. Recombinant proteins dominate the growing list of the more than 200 approved biotherapeutic agents with targeted antibodies, fusion proteins and receptors; cytokines; hormones; enzymes; proteins involved in blood-clotting, homeostasis and thrombosis; vaccines; botulinum neurotoxins; and, more recently, biosimilar preparations, comprising the majority of approved biologics. Written with clinicians, other health care professionals, and researchers in mind, Safety of Biologics Therapy examines, in a single volume, the full range of issues surrounding the safety of approved biologic therapies. A good understanding of the risks and safety issues of modern biologics therapy is increasingly being demanded of all those connected with their development, handling, prescribing, administration and subsequent patient management. In addition to being of great value to clinicians in all branches of medicine, and to nurses, pharmacists and researchers, this book will prove invaluable for students taking undergraduate and graduate courses in the above disciplines and in the biomedical sciences.
