it was found that the dextran 36,500 mw fraction produced aggregation behavior for red cells and vesicles similar to red cell-red cell aggregation in dextran 70,000-150,000 mw fractions , when the vesicle surface charge density was comparable with that of normal red cells ( i.e. , pc/ps ratio of -3:1 ) .
