Cell Culture Engineering IV, Improvements of Human Health covers the latest approaches to improving the cell host through improved understanding of the molecular biology, the development of novel vaccines, approaches to bioreactor design and operation, monitoring techniques in process control and quality related topics. The work was carefully put together as one result of the Cell Culture Engineering IV Meeting held in San Diego, U.S.A. in 1994, however, the book may not be perceived as a proceedings volume - the criteria of the book series apply. For cell biologists, biochemists, molecular biologists, immunologists and other disciplines related to cell culture engineering, working in the academic environment, as well as in (biotechnology or pharmaceutical) industry.
