Abstract:
New developments in magnetic labelling techniques for cells and microspheres have extended the useful range of magnetic separation, particularly high gradient magnetic separation, into biotechnical areas. The basic magnetic principles involved are reviewed and representative samples of labelling techniques and results drawn from the past three years are presented. Illustrative examples of large scale operation in other industries are also presented, demonstrating the potential of the biotechnological applications.
