Tween® 20 (Polisorbat)

Numer katalogowy: (ICNA11TWEEN201)

Producent: MP Biomedicals

Opis: 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%.

j.m.: 1 * 500 mL

Tween® 80 (Polisorbat), liquid, Cell Culture Grade

Numer katalogowy: (ICNA02194725.1)

Producent: MP Biomedicals

Opis: Tweens® are a 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® 80 has been widely used in biochemical applications including: solubilizing proteins, isolating nuclei from cells in culture selective protein extraction growing of tubercule bacilli, and emulsifying and dispersing substances in medicinal and food products. It has little or no activity as an anti-bacterial agent. It has been shown to have an adverse effect on the antibacterial effect of methyl paraben and related compounds. Non-ionic detergent used for selective protein extraction and isolation of nuclei from mammalian cell lines.
Soluble/miscible in water to give a clear yellow solution; miscible with alcohol, dioxane, and ethyl acetate; practically insoluble in liquid paraffin and fixed oils (such as mineral oil).
Autoclaving of solutions is not recommended. Sterile filtering is suggested with a 0.22 micron filter. Tween® may need to be warmed to about 40 °C and alternated with portions of hot distilled water while being poured through the filter.
Store at Room Temperature (15-30 °C).
