Used as a non-ionic surfactant in biochemical and biotechnological applications, particularly in electrophoresis and membrane washing steps during Western blotting. Helps in blocking and reducing non-specific binding when used in buffer solutions. Commonly employed in cell lysis and protein solubilization due to its mild nature, preserving protein activity. Also utilized in cosmetic formulations and pharmaceuticals as an emulsifier and stabilizer. Suitable for use in diagnostic kits and assays requiring low interference with enzymatic reactions.
