General description
Tween 20, also referred to as poly(oxyethylene)n-sorbitan-monolaurate, is a non-ionic surfactant. It is mainly used in membrane research.
Application
Tween 20 is used for:
- solubilizing membrane proteins during isolation of membrane-protein complexes.
- a subsequent protein detection by UV light absorption, due to its low UV absorbance.
- ELISA (enzyme-linked immunosorbent assay) and immunoblots.
Quality
Purity: <2 ppm peroxide content (as H2O2), <200 μM carbonyls, <100 μS conductivity. Specially purified for membrane research.
Physical form
10% (w/v) aqueous solution under nitrogen, supplied in injection glass bottles.
Preparation Note
Working concentration: >10 mg/mg membrane lipid
Other Notes
For life science research only. Not for use in diagnostic procedures.

The objectives of this work were to determine the effects of nonionic surfactants (Tween 20 and Tween 80) on agitation-induced aggregation of the recombinant fusion protein, Albutropintrade mark (human growth hormone genetically fused to human albumin), and to characterize the
