Thermo Scientific Sodium Dodecyl Sulfate (Lauryl) is standard-grade SDS detergent for use in protein polyacrylamide gel electrophoresis (PAGE).
Features of Sodium Dodecyl Sulfate (Lauryl):
• Popular anionic detergent for a variety of protein methods • Especially useful for denaturing polyacrylamide gel electrophoresis (SDS-PAGE) • Common component of cell lysis buffers
This lauryl-grade sodium dodecyl sulfate (SDS) is a popular anionic detergent for routine protein electrophoresis and cell lysis methods. The formulation is a mixture of several different alkyl sulfate chain lengths (C10 to C18).
