DELAYED HYPERSENSITIVITY IN MAN: TRANSFER BY LYMPHOCYTE PREPARATIONS OF PERIPHERAL BLOOD.
Eight passive transfers of delayed skin hypersensitivity to pollen antigens were achieved by injection of lymphocyte preparations of peripheral blood from sensitized donors into previously nonreactive subjects. The granulocytes and platelets were removed from the blood of each donor by passage through a column of glass beads coated with silicone.
