Abstract
The present application relates to a method for removing pathogens from a transfusion grade platelet composition. The method comprises the steps of passing a platelet preparation through a first tangential flow filtration (TFF) device having a TFF filter, and collecting a retentate from the TFF device, wherein the retentate comprises filtered platelets to be used for transfusion. The platelet preparation comprises a platelet activation inhibitor and an anti-coagulant. During the TFF process, a diafiltration solution is added to the retentate to maintain the volume of the platelets.
