Process for rosetting human B lymphocytes with Rhesus monkey erythrocyte

摘要

Human peripheral blood lymphocytes are stimulated with either a polyclonal activator or an antigen which gives rise to immunologically activated B lymphocytes. These activated B lymphocytes are separated from non-activated B lymphocytes by relying on the fact that activated B lymphocytes possess a surface marker; the ability to rosette Rhesus monkey lymphocytes (RhMRBC), not found on their non-activated counterparts. Separation is achieved by rosetting with RhMRBC and subsequent density centrifugation of cells.
