to discriminate the stages of maturation arrest of leukemic b cells , we have investigated the cell surface expression of fc epsilon rii ( h107 antigen ) on leukemic b cells from 6 patients with chronic type b-lymphocytic leukemia ( b-cll ) by a double staining method combined with cytofluorometry , and their production of soluble fc epsilon rii by an elisa technique .
