Popis: Polymerized human hemoglobin (PolyhHb) is being studied as a possible red blood cell (RBC) substitute for use in scenarios where blood is not available. While the O carrying capacity of PolyhHb makes it appealing as an O therapeutic, the commercial PolyhHb PolyHeme® (Northfield Laboratories Inc., Evanston, IL) was never approved for clinical use due to the presence of large quantities of low molecular weight polymeric (LMW) Hb species (in vivo. Previous bench-top scale studies in our lab demonstrated the ability to synthesize and purify PolyhHb using a two-stage tangential flow filtration (TFF) purification process to remove almost all undesirable Hb species (>0.2 µm and
