This is an easy-to-use 10% (w/v) solution of purified NP-40 detergent for use in routine and high-demand protein research methods and molecular biology techniques. NP-40 is a nonionic polyoxyethylene surfactant that is most frequently used as a component of cell lysis buffers or other solutions intended to extract and solubilize proteins.

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.
