title: The effects of two neutral polymers on the geometry and deformability of the human erythrocyte.
abstract: Polyvinylpyrrolidone and dextran decrease cellular deformability. Changes in volume do not wholly account for the changes which imply a stiffening of the plasma membrane. The effects differ from those induced by charged macromolecules.
