Abstract
Dielectrophoresis has been used to enrich selected cell subpopulations in a mixed cell population by exploiting differential dielectric properties. Six-fold enrichment of stem cells expressing the CD34+ antigen has been achieved for bone marrow samples and peripheral blood, without the requirment for initial chemical treatment associated with immunoadsorption techniques.
