Polysucrose 70 is widely used in biomedical research for its role in cell separation and density gradient centrifugation. It is particularly valuable in isolating specific cell types, such as lymphocytes, from whole blood samples. Its high molecular weight and low osmolality make it ideal for creating gradients that separate cells based on density without causing damage or osmotic stress. This chemical is also employed in the purification of subcellular organelles, such as mitochondria and nuclei, enabling detailed studies of cellular components. Additionally, Polysucrose 70 is utilized in vaccine development and immunology research to enhance the stability and efficacy of biological preparations. Its inert nature ensures minimal interference with cellular functions, making it a reliable tool in various experimental and diagnostic applications.
