Tween® 20, belonging to the family of polysorbates, is a non-ionic surfactant, which effectively prevents non-specific reactions between antibodies, antigens and other molecules (1, 2). The detergent is used in sample preparation and signal transduction research for solubilisation of membrane components (3) and in density centrifugation of viruses (4). Tween® 20 serves as an emulsifier for the preparation of stable oil-in-water emulsions.
