Application
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 150 may be used to study iron delivery to cells, cell membrane permeabilization and red blood cell aggregation.
L'utilisation de dextrans comme longs bras hydrophiles améliore les performances des protéines immobilisées qui agissent sur les macromolécules.
Notes préparatoires
With the exception of the highest MW dextran, D5501 (MW range = 5 million to 40 million), dextrans are very water soluble. Sigma tests the solubility of dextrans at concentrations generally exceeding 30 mg/ml in water. Dextrans are also freely soluble in DMSO, formamide, ethylene glycol, and glycerol. Neutral-aqueous dextran solutions can be sterilized by autoclaving at 110-115oC for 30 to 45 minutes. Dextran can be hydrolyzed by strong acids at high temperatures. The terminal reducing end group of dextran can be oxidized in alkaline solutions.
