Abstract
A method of producing a platelet solution replaced with an artificial preservation solution includes a filtering step of carrying out cross-flow filtration of a platelet solution under the conditions of Formula (1) at an inlet wall shear rate of 25 to 1500 susing a separation membrane whose surface which contacts with the platelet solution has an average pore size of not less than 0.1 μm and less than 2.0 μm, thereby obtaining a concentrated platelet solution; and a mixing step of mixing the concentrated platelet solution with an artificial preservation solution to obtain the platelet solution replaced with an artificial preservation solution:1.0×10<()/(γ×μ)≦2.5×10(platelets/(hr·m·Pa))  (1)
