Conveniently packaged Tween-20 solutions for use in protein extraction and immunoassays.

Thermo Scientific Surfact-Amps* 20 Detergent Solution is highly-purified Tween*-20 detergent stabilized and supplied as a 10% solution in 10mL glass ampules. This is an easy-to-use 10% (w/v) solution of purified Tween-20 detergent for use in routine and high-demand protein research methods and molecular biology techniques. Tween-20 is a nonionic polyoxyethylene surfactant that is most frequently added to PBS or TBS wash buffers for ELISA, Western blotting and other immunoassay methods.

Highlights of Tween-20 Surfact-Amps Detergent Solution:

• Tween-20 – a popular nonionic detergent for use in immunoassay wash buffers
• Accurate – precise 10% detergent solution in ultrapure water
• Easy-to-use – solution is simple to dispense and dilute for use
• Exceptionally pure – less than 1.0µeq/mL peroxides and carbonyls
• Stable – packed in glass ampules under inert nitrogen gas

About Surfact-Amps Detergent Solutions:

Surfact-Amps Detergent Solutions (10% w/v) provide unsurpassed purity, quality and stability. Unlike neet detergents, which are extremely viscous, Surfact-Amps 10% Solutions are easy to pipette and accurately dispense. The surfactant solutions are carefully prepared and packaged under nitrogen in glass ampules, ensuring their stability and eliminating the accumulation of peroxides and degradation products.
