Alkali Scientific Tween 80 (Polyoxyethylenesorbitan, Monooleate), 1 L
Tween 80 (Polyoxyethylenesorbitan Monooleate), 1L, is a nonionic detergent commonly used as an emulsifier and solubilizing agent in laboratory settings. The larger 1L bottle is suitable for high-throughput applications such as protein extractions, cell membrane solubilization, and the preparation of stable emulsions for biochemical and molecular biology assays. Tween 80’s gentle nature makes it ideal for use in experiments where it is essential to preserve the functionality of proteins, lipids, and other cellular components. It is widely used in research related to cell culture, immunology, and pharmaceutical development, where consistent and mild detergent action is required.
