NP-40 Surfact-Amps™ Detergent Solution



Thermo Scientific Surfact-Amps NP-40 Detergent Solution is highly-purified NP-40 detergent stabilized as a 10% solution in your choice of either 10 mL glass ampules or two sizes of HDPE-plastic bottles.

Features of Surfact-Amps NP-40 Detergent Solution:

  • NP-40—a nonionic detergent for use in various protein methods
  • Accurate—precise 10% detergent solutions in ultrapure water
  • Easy-to-use—solutions are simple to dispense and dilute for use
  • Exceptionally pure—less than 1.0µeq/mL peroxides and carbonyls
  • Stable—packaged under inert nitrogen gas in HDPE bottles

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 or non-leaching HDPE bottles, ensuring their stability and eliminating the accumulation of peroxides and degradation products.
