Description Tween-20 Surfact-Amps Detergent Solution
Quantity 1L

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.

Surfact-Amps™ Detergent Solutions (10% w/v) provide unsurpassed purity, quality and stability. Unlike neat 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.
