Sodium Dodecyl Sulfate (Lauryl SDS)


Electrophoresis and lysis buffer grade SDS formulation.

Sodium Dodecyl Sulfate (Lauryl SDS)

Thermo Scientific Sodium Dodecyl Sulfate (Lauryl) is standard-grade SDS detergent for use in protein polyacrylamide gel electrophoresis (PAGE).

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).

Highlights:

  • Popular anionic detergent for a variety of protein methods
  • Especially useful for denaturing polyacrylamide gel electrophoresis (SDS-PAGE)
  • Common component of cell lysis buffers
