METHOD FOR REMOVING UNMODIFIED HEMOGLOBIN FROM CROSS-LINKED HEMOGLOBIN SOLUTIONS INCLUDING POLYMERIC HEMOGLOBIN WITH A HIGH TEMPERATURE SHORT TIME HEAT TREATMENT APPARATUS
A METHOD HEAT TREATMENT OF CROSS-LINKED HEMOGLOBIN SOLUTIONS INCLUDING POLYMERIC HEMOGLOBIN IS DISCLOSED. THE METHOD INVOLVES CONTACTING THE HEMOGLOBIN SOLUTION WITH A HIGH TEMPERATURE SHORT TIME HEAT TREATMENT APPARATUS. THE HIGH TEMPERATURE SHORT TIME PROCESS THERMALLY DENATURES UNMODIFIED TETRAMERIC HEMOGLOBIN (HEMOGLOBIN DIMER FORM), PROTEIN IMPURITIES (E.G. IMMUNOGLOBIN-G, SERUM ALBUMIN), BACTERIA, AND VIRUSES SO THAT RENAL INJURY, VASCULAR DETRIMENTAL EFFECTS AND OTHER TOXICITY REACTIONS CAN BE AVOIDED.
