Polysucrose 800 is widely used in biomedical research and clinical applications, particularly in the field of cell separation and density gradient centrifugation. Its high molecular weight and solubility make it an ideal medium for creating density gradients that enable the isolation of specific cell types, such as lymphocytes, monocytes, and other blood cells. This is especially useful in immunology and hematology studies, where purified cell populations are required for analysis or therapeutic purposes.

In addition, Polysucrose 800 is employed in the preparation of vaccines and as a stabilizing agent for biological samples. Its non-toxic and inert nature ensures that it does not interfere with cellular functions or biochemical processes, making it a reliable choice for maintaining the integrity of cells and tissues during experimental procedures. Furthermore, it is used in diagnostic assays to enhance the separation of components in complex biological fluids, aiding in the accurate detection of biomarkers or pathogens. Its versatility and biocompatibility have established it as a valuable tool in both research and clinical settings.
