CM-dextran is widely used in biomedical research and pharmaceutical applications due to its biocompatibility and solubility. It serves as a drug delivery carrier, enabling targeted release of therapeutic agents in specific tissues or cells. In tissue engineering, it acts as a scaffold material to support cell growth and regeneration. CM-dextran is also utilized in diagnostic assays, such as fluorescence labeling, to track biological processes. Additionally, it is employed in chromatography as a stationary phase for separating biomolecules based on size or charge. Its ability to modify surface properties makes it valuable in coating medical devices to improve biocompatibility and reduce immune responses.
