title: The immunological properties of stroma-free polyhemolysate containing catalase and superoxide dismutase activities prepared by polymerized bovine stroma-free hemolysate.
abstract: Crosslinking of ultrapure hemoglobin, crystalline catalase, and superoxide dismutase resulted in a soluble nanodimensional complex of polyhemoglobin-catalase-superoxide dismutase. A less expensive and more convenient way is to crosslink bovine stroma-free hemolysate (stroma-free hemolysate) that already contains hemoglobin, catalase, and superoxide dismutase into polyhemoglobin with catalase and superoxide dismutase activities (stroma-free polyhemolysate) [21]. The objective of the present study is to evaluate the immunological properties of this stroma-free polyhemolysate. Each of three groups of rats received weekly subcutaneous injections of one of the stroma-free polyhemolysate, stroma-free hemolysate, and saline for four weeks. One week after the four cycles of weekly immunization, serum and plasma were collected for C3a complement activation tests and Ouchterlony antibody-antigen precipitation tests, respectively. Results show that stroma-free polyhemolysate retained significant antioxidant enzyme activity. The C3a complement activation test and Ouchterlony test show that four weekly subcutaneous injections of bovine stroma-free polyhemolysate did not result in any immunological reaction in rats when tested this way.
