The function of human white cells is dependent on a complex machinery involving a network of proteins. Their identification has posed a puzzle for scientists for many years and this book comprises the proceedings of the latest in a series of international meetings that have identified many ofthese entities and studied their function and clinical importance. Leucocyte Typing VII provides the definitive reference for all those working with antibodies recognising marker molecules on white blood cells. Sorting and tracing white blood cells is important in a range of clinical settings, butespecially in the diagnosis of leukaemias. There is a concerted action by regulatory bodies looking for a standard against which these 'biologicals' can be assessed. The book contains the assembled work of many laboratories worldwide which jointly evaluated many hundered different monoclonalantibodies. The results of the collaborative effort reported at the meeting are published in Leucocyte Typing VII. A unique feature of this book is the complete guide to all available CD- antigens. This book is the standard reference for immunologists, cell and molecular biologists,haematologists, and pathologists working on white cell differentiation. It provides immunologists and biochemists with an up to date summary of the current knowledge of molecular aspects of different categories of human white cells (and endothelial and red cells) and provides hematologists andoncologists with information relevant to their clinical practice and research.
