Chapter 5.4: Extraction of Superoxide Dismutase, Catalase and Carbonic Anhydrase from Stroma-free Red Blood Cell Hemolysate for the Preparation of the Nanobiotechnological Complex of PolyHemoglobin-superoxide Dismutase-Catalase-carbonic Anhydrase

We report a novel method to simultaneously extract superoxide dismutase (SOD), catalase (CAT) and carbonic anhydrase (CA) from the same sample of red blood cells (RBCs). This avoids the need to use expensive commercial enzymes, thus allowing this to be cost effective for large-scale production of a nanobiotechnological polyHb-SOD-CAT-CA with enhancements to all three RBC functions. The best concentration of phosphate buffer for ethanol-chloroform treatment results in good recovery of CAT, SOD and CA after extraction. Different concentrations of the enzymes can be used to enhance the activity of polyHb-SOD-CAT-CA to 2, 4 or 6 times that of RBCs.
