PROBLEM TO BE SOLVED: To provide a filter for selectively removing leukocytes from a cell suspension typified by blood, and particularly to reduce leukocytes while suppressing loss of red blood cells, platelets, and plasma components extremely. To provide a leukocyte selective removal filter for removing selectively and efficiently. SOLUTION: In a filter for selectively removing leukocytes from blood containing a filter substrate coated with a polymer, the coating amount of the polymer on the filter substrate is 100 mg (polymer) / m 2 (the total surface area of the filter substrate) Per) and a pressure loss due to aeration is not more than twice the pressure loss due to aeration of the filter substrate. |
