Therefore, the purpose of this open-end treatise is to acquaint the reader with some of the basic principles, instrumentation, and procedures pres- ently in practice at various laboratories around the world and to present some typical applications of each technique to particular biological prob- lems. To this end, I was fortunate to obtain the contribution of certain leading scientists in the field of cell separation, people who in their pioneer- ing work have struggled with the particular problems involved in separating living cells and in some way have won.
