Storage: Room Temperature
Polysorbate 20 is nonionic surfactants derived from sorbitan ester, it is soluble or dispersible in water but differ widely in organic and oil solubility.
Polysorbate 20 is typically used as an emulsifying agent for the preparation of stable oil-in-water emulsions, particularly in pharmaceutical applications. It is also used in pre-extraction of membranes to remove peripheral proteins & as a blocking agent on nitrocellulose at a typical concentration of 0.05%.
Series of nonionic surfactants derived from sorbitan esters. They are soluble or dispersible in water but differ widely in organic and oil solubilities. Used as oil-in-water emulsifiers in pharmaceuticals, cosmetics, cleaning compounds, etc.

TWEEN 20 is a nonionic detergent widely used in biochemical applications, such as emulsifying agents for the preparation of stable oil-inwater emulsions. It has been used in preextraction of membranes to remove peripheral proteins. TWEEN 20 has been used as a blocking agent for membrane based immunoassays at a typical concentration of 0.05%. TWEEN 20 can be used for lysing mammalian cells at a concentration of 0.05 to 0.5%.

TWEEN 20 is a polyoxyethylene sorbitol ester.

Typical Working Concentration:
Extraction of membrane-bound proteins: 2%; blocking agent for membrane based immunoassays at a typical concentration of 0.05%; lysing mammalian cells at a concentration of 0.05 to 0.5%.
