Description générale

ECO Tween® 80, also known as Polyoxyethylenesorbitan monooleate, is a bio-based, nonionic detergent manufactured from a natural fatty acid. This surfactant, derived from natural sources, provides various functional advantages, such as detergency, emulsification, and wetting. Its versatility makes it well-suited for a variety of applications in biochemical and biological research, with common uses including cell lysis, protein extraction, nuclei isolation and cell fractionation.
We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Green Chemistry. This product is a biobased surfactant and is aligned with the 7th principle of Green Chemistry "Use of Renewable Feedstocks" and the 10th principle "Design for Degradation".

Application

Non-ionic detergent used for selective protein extraction and isolation of nuclei from mammalian cell lines.
TWEEN® 80 has been used in drug vehicle solution for specific injections in mice and rats. It has been used for the determination of esterase activity in bacterial cells.

Actions biochimiques/physiologiques

TWEEN® 80 is a polysorbate surfactant which helps in stabilizing proteins and in protein membrane studies. It is regularly used for the extraction of membrane proteins and isolation of nuclei from cells.

Previous reports show that vagal afferent innervation of the stomach eventually regenerates from surviving nodose ganglion (NG) neurons after subdiaphragmatic vagotomy. Systemic capsaicin treatment destroys gastric vagal afferent neurons expressing vanilloid receptor 1 (VR1). However, it is not known whether
