Abstract: Platelet resuspension solutions, platelet storage solutions and systems for processing platelet-containing biological fluids are disclosed, wherein a platelet resuspension solution comprises an aqueous solution having a pH in the range of from about 4 to about 6: dextrose; and citrate; wherein the solution is substantially free of adenine, and wherein a platelet storage solution comprises an aqueous solution having a pH in the range of from about 6.6 to about 7.8; at least one buffer: dextrose, and citrate; wherein the solution is substantially free of adenine.

Abstract: A method for preparing red blood cell concentrates uses a single additive solution composition having a reduced citrate concentration both for anticoagulation of whole blood and for preserving red blood cells in storage.

Abstract: The invention is a sterile, plasma-free storage medium for blood components including red blood cells and for platelets processed separately or together. The red cell storage medium includes adenine and a physiologically compatible, aqueous electrolyte solution. In one liter of this electrolyte solution there is between about 3.0 grams and about 25.0 grams of dextrose, between about 3.0 grams and about 6.0 grams of sodium citrate, and between about 2.0 grams and about 4.2 grams of sodium bicarbonate. The red cell storage medium is isotonic and has a pH in a range of between about 6.8 and about 7.4. The red cell storage medium is capable of storing and preserving red cells for at least 49 days.

Abstract: A first aspect of the present invention is a blood platelet preparation comprising blood platelets, an adenylate cyclase stimulator, a phosphodiesterase inhibitor, a thrombin inhibitor, and a plasmin inhibitor. A second aspect of the present invention is a plasma-free platelet storage medium containing dextrose, sodium citrate, sodium bicarbonate, and a platelet activation inhibitor, with a preferred platelet activation inhibitor comprising an adenylate cyclase stimulator in combination with a phosphodiesterase inhibitor. A third aspect of the present invention is a process for producing a plasma-free platelet preparation comprising producing platelet-rich plasma (PRP) from whole blood, adding a platelet activation inhibitor thereto, centrifuging the PRP to deposit the platelets on the bottom of the centrifuge container, removing the platelet-free plasma supernatant therefrom and adding a plasma-free liquid platelet storage medium thereto.
