Rheology of erythrocyte suspensions: dextran-mediated aggregation of deformable and nondeformable erythrocytes

Abstract
Dextran (dx) in excess of 40,000 MW can induce weak cell aggregation of native human erythrocytes (RBC) and formaldehyde-fixed RBC (F-RBC) by macromolecular bridging. Cellular aggregation is measured both microscopically and by a rheological method i
