<p>A filter medium for selectively removing leukocytes from a suspension thereof, which is prepared from a porous element with a mean pore diameter of 1-25 νm and wherein the total pore volume of the element is 0.40-0.95 ml/ml of the element and the volume of pores with diameters of 1-30 νm accounts for at least 90 % fo the total pore volume; and a filter packed therewith for use in selectively removing leukocytes. The use of this medium serves to remove leukocytes to a residual leukocyte content of 10-4 or less without increasing the pressure loss and to reduce the size of a filter for selectively removing leukocytes.</p> |
