Dextrans are used in many applications as platelet aggregants, plasma volume extenders, osmotic pressure regulators, stabilizers, organ separation media, matrix components, copolymers, microcarriers, binding agents, viscosity modifiers, antithrombotics, lubricants and physical structure components.
Dextrans may be used as long hydrophilic spacer arms to improve the performance (freedom of movement) of conjugated/bound proteins. Dextrans may be derivatized for use in biosensor systems.
Dextran 40 may be derivatized for use as a cell permeation reagent.
Use of dextrans as long and hydrophilic spacer arms improves the performance of immobilized proteins acting on macromolecules.
