Tween 20 (Polyoxyethylenesorbitan Monolaurate), 4L, is a highly effective nonionic detergent used as an emulsifying agent in various biological and biochemical applications. This large bottle size is ideal for laboratories requiring frequent use of Tween 20 in protein extractions, solubilizing lipids, and preparing buffer solutions. It is particularly useful in maintaining the stability of proteins and other macromolecules during solubilization and for creating stable emulsions. The detergent is often utilized in assays, including enzyme-linked immunosorbent assays (ELISA), and in cell culture protocols that require non-disruptive detergents. This format provides excellent value for high-volume laboratories.
