Used extensively in biomedical research for density gradient centrifugation, particularly in the preparation of Ficoll-Paque solutions to isolate mononuclear cells from blood. Its inert nature and ability to form stable density gradients make it ideal for cell separation without causing damage. Also employed in drug delivery systems and as a plasma expander in experimental models due to its biocompatibility and water-solubility. Commonly used in immunology and cell biology workflows requiring high cell viability and purity.
