Product Description

Polysorbate 20

Application Notes

Polysorbate 20 is used as emulsifying agent for the preparation of stable oil-inwater emulsions in pharmaceuticals, cosmetics, cleaning compounds. Polysorbate 20 has been used in preextraction of membranes to remove peripheral proteins (used at 2% for extraction of membrane-bound proteins). It has been used as a blocking agent for membrane based immunoassays at a typical concentration of 0.05%. It can be used for lysing mammalian cells at a concentration of 0.05 to 0.5%. It is a nonionic detergent widely used in biochemical applications.

Usage Statement

Research Use Only (RUO). Ready for CE IVD labeling of clinical applications.

Key Applications

Non-ionic detergent

Sterilization of Solutions Autoclaving of solutions is not recommended. Sterile filtering is suggested with a 0.22 micron filter. Polysorbate 20 may need to be warmed to about 40 °C and alternated with portions of hot distilled water while being poured through the filter.
Storage and Handling Store at Room Temperature(15-30 °C).
