Tween 20 [Polyoxyethylenesorbitan Monolaurate]

Tween 20 (Polyoxyethylenesorbitan Monolaurate) is a nonionic surfactant supplied as a viscous liquid. It is widely used in biochemical, pharmaceutical, and molecular biology research for its emulsifying, solubilizing, and stabilizing properties.

In laboratory applications, Tween 20 is used to prevent protein aggregation, stabilize enzymes, enhance solubility of hydrophobic compounds, and as a component in buffers, cell culture media, and immunological assays. Its mild, non-denaturing nature ensures proteins and biomolecules maintain their structure and activity during experimental procedures.
