Used extensively in biomedical research as a plasma expander to maintain blood volume in experimental models without interfering with blood chemistry. Commonly employed in cell separation techniques due to its ability to create density gradients, enabling isolation of specific cell types such as lymphocytes from whole blood. Also utilized in drug delivery systems where controlled release is required, thanks to its biocompatibility and water-soluble properties. Frequently found in diagnostic assays as a stabilizing agent to preserve enzyme and protein activity during storage and use.
