A simple method for the elimination of platelets from the lymphocyte-platelet mixture by sucrose

A method for the separation of lymphocytes from human blood by Ficoll-Hypaque density centrifugation, with removal of platelets by a single sucrose solution with a density of 65%, is presented. The Ficoll-Hypaque-sucrose method gives a good yield of lymphocytes, high viability and purity, and relatively low contamination with erythrocytes and platelets.
