b'DetergentsEasy-to-pipette, highly purified Surfact-Amps 10% solutionsThermo Scientific Surfact-Amps Detergent Solutions are easy-to-use 10% (w/v) solutions of highly purified detergents that can be used in routine and high-demand protein research methods and molecular biology techniques (Figure 3). These formulations provide high purity, quality, and stability. Unlike neat detergents, which are extremely viscous, Surfact-Amps 10% solutions are easy to pipet accurately. The surfactant solutions are carefully prepared and packaged under nitrogen in glass ampules or non-leaching HDPE bottles, helping to ensure their stability and minimizing the accumulation of peroxides and degradation products.Highlights: Accurateprecise 10% detergent solution in ultrapure water Easy to usesolution is simple to dispense and dilute Exceptionally pureless than 1 eq/mL peroxides and carbonyls (Tables 2 and 3) Stablepackaged under inert nitrogen gas in glass ampules or HDPE bottlesHydrophobic Hydrophilictail headFigure 3.
