Dextran protection of erythrocytes from low‐pH‐induced hemolysis

Abstract
Low‐pH‐induced hemolysis of erythrocytes is inhibited by dextrans. The protective effect was observed with dextrans larger than 40 kDa. Electron microscopy showed dextrans of 150 kDa in a tight association with the erythrocyte membrane. These results indicate that dextrans stop the low‐pH‐induced hemolysis by interacting with the acid‐induced defects in the erythrocyte membrane [(1989) Biochim. Biophys. Acta, in press.
