20100233671 | FREEZE-DRIED PLASMA FORMATS FOR THE TRAUMA CARE FIELD - Disclosed are freeze-dried plasma formats specifically designed for the trauma care field. Blood plasma is subjected to a glucose removal step, a protein fraction up-concentration step and addition of stabilizers prior to freeze-drying. Preferable stabilizers are glutamine dipeptides, glutamine and glycine. The glutamine based formulation is added direct to plasma and serves three main purposes: 1) Increases stability of plasma proteins and stabilizes pH in freeze-dried state; 2) Increases stability of plasma proteins against Gamma Irradiation and thus allows for the application of a terminal sterilization step; 3) Introduces supplements beneficial to the trauma patient. | 09-16-2010 |
20100273141 | Glycine stabilized lyophilized plasma - The invention is directed to stabilized whole-cell plasma, which retains the integrity and overall stability of the proteins and other macromolecules of the plasma. Stabilization is accomplished by the addition of glycine to plasma which allows for stabilization prior to freeze drying. Glycine, in the presence of the salt concentration in the plasma, does not recrystallize and acts as a superior stabilizer for the lyophilized plasma. The stability of the freeze dried plasma may be further improved by addition of protectants including calcium chloride, trisodium citrate, hydroxyethyl starch, ammonium sulfate and citric acid to maintain physiologic pH. Superior stability for a wide variety of plasma proteins and functions is shown. A system for the large scale preparation of sterile lyophilized plasma is also provided. | 10-28-2010 |
