Abstract: A suitable container for plasma lyophilization has been designed for lyophilization (lyo-bag), storage, reconstitution and administering of blood products. A rigid support frame for use with a lyo-bag with sidewalls was designed as an external removable supportive system, which provides the necessary stability for the flexible container during lyophilization. A removable bottom wall support sheet was designed for use with any flexible container for lyophilization.

Abstract: A lyophilized platelet preparation, which is preferably a platelet enhanced plasma preparation, was obtained by stabilizing separated platelets with glyceraldehyde. In contrast to fixed preparations of cells, the platelet preparation is made and provided without toxins. Not fixing the platelets according to the invention provides increases utility and allows for the ability to change volume. The platelets are combined with a glyceraldehyde analog for a few hours at slightly elevated temperatures (about 35° C.) and then freeze dried and on reconstitution with distilled water exhibit morphological and physiological properties similar to that of native platelets, and superior to untreated, lyophilized platelets.
