When blood is caused to flow through {HEAD ~ the filter unit} having {TAIL ~ a fiber bulk density} of from 0.04 to 0.25 gram/cubic centimeter and an average fiber diameter of from 7 to 10 microns and then the entrapped leukocytes are collected from the filter unit, the resulting granulocytes and monocytes exhibit good motility and phagocytic ability, and the resulting lymphocytes can be blastotransformed by various mitogens such as phytohemagglutinin and pokeweed mitogen to an extent similar to that of lymphocytes prepared by other methods
