Dextran sulfate sodium salt is widely used in biochemical and medical research due to its ability to mimic certain biological processes. It is commonly employed to induce colitis in animal models for studying inflammatory bowel diseases, providing insights into disease mechanisms and potential treatments. In molecular biology, it serves as a competitive inhibitor for binding assays, particularly in studies involving proteins and nucleic acids. Additionally, it is utilized in cell culture to prevent cell clumping and improve cell separation. Its anticoagulant properties make it useful in blood-related research, such as studying blood clotting mechanisms. Dextran sulfate sodium salt also plays a role in drug delivery systems, where it helps stabilize and enhance the solubility of therapeutic agents.
