This book has evolved as a result of the success of the post-experience courses in monoclonal antibody technology run by the Department of Biochemistry, University of Wales College of Cardiff. The authors have designed it to provide all the information required by a competent scientist to produce monoclonal antibodies, from basic tissue culture techniques, through immunisation strategies and screening test design, to the production of hybridoma cell lines and basic antibody characterisation, purification and labelling. The protocols are presented in a clearly distinguishable format for use at the laboratory bench. The concluding chapter provides an overview of the current status of human hybridoma production and antibody engineering using techniques of molecular biology. This book is essential reading for graduates in the biological sciences and in medicine who are involved in the making and using of monoclonal antibodies in commercial, university and medical laboratories.
