Gas plasma treated porous medium and method of separation using same

摘要

A leukocyte depletion medium (36) for removing leukocytes from a biological fluid comprising a porous medium (36) which has been treated with a plasma generated from a mixture of gases. In a method for the separation of leukocyte from a biological fluid the fluid is passed through the leukocyte depletion medium (36) and leukocytes are depleted from the fluid.
