Descripción

Descripción general

Tween 20, also referred to as poly(oxyethylene)_n-sorbitan-monolaurate, is a non-ionic surfactant. It is mainly used in membrane research.

Aplicación

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.

Calidad

Purity: <2 ppm peroxide content (as H₂O₂), <200 μM carbonyls, <100 μS conductivity. Specially purified for membrane research.

Forma física

10% (w/v) aqueous solution under nitrogen, supplied in injection glass bottles.

Nota de preparación

Working concentration: >10 mg/mg membrane lipid
