Product Description

Sodium Dodecyl Sulfate

Application Notes

Used to solubilize and denature proteins for denaturing-PAGE. Most proteins bind SDS in a ratio of 1.4 g SDS per gram of protein. The charges intrinsic to the protein become insignificant compared to the overall negative charge provided by the bound SDS. The charge to mass ratio is essentially the same for each protein and will migrate in the gel based only on their size.

Usage Statement

Research Use Only (RUO). Ready for CE IVD labeling of clinical applications.

Key Applications

Detergents||Electrophoresis Chromatography||Western Blotting
