fluorescence-activated cell sorting ( facs ) of pbl on the basis of mo2 expression results in a population of mo2+ cells ( morphologically monocytes ) that is selectively active in phagocytosis and cytolysis of antibody-sensitized human erythrocytes , and a population of mo2- cells ( morphologically lymphoid cells ) that is nonphagocytic but selectively active in natural killing .
