Overview: Presently, the need for methods involving separation, identification, and characterization of different kinds of cells is amply realized among immu- nologists, hematologists, cell biologists, clinical pathologists, and cancer researchers. Unless cells exhibiting different functions and stages of differ- entiation are separated from one another, it will be exceedingly difficult to study some of the molecular mechanisms involved in cell recognition, specialization, interactions, cytotoxicity, and transformation. Clinical diag- nosis of diseased states and use of isolated cells for ther
