Dextran is widely used in medical and pharmaceutical applications due to its biocompatibility and unique properties. It is commonly employed as a blood plasma volume expander in cases of shock or severe blood loss, helping to maintain blood pressure and circulation. In laboratory settings, dextran serves as a stabilizer and thickening agent in various biochemical assays and cell culture media. It is also utilized in drug delivery systems to enhance the solubility, stability, and targeted release of therapeutic agents. Additionally, dextran is a key component in certain chromatography techniques, aiding in the separation and purification of biomolecules. Furthermore, it is used as a coating agent on medical devices to prevent blood clotting. Its applications extend to the food industry, where it acts as a texturizer and stabilizer in products like sauces and dressings.
