Application Anionic detergent   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. 性质 grade for electrophoresis description anionic assay ≥98.5% (GC) mol wt micellar mol wt 18,000 aggregation number 62 turbidity <2.5 NTU CMC 7-10 mM(20-25°C) mp 204-207 °C(lit.) transition temp cloud point >100 °C anion traces chloride (Cl-): ≤500 ppm   phosphate (PO43-): ≤10 ppm cation traces heavy metals (as Pb): ≤10 ppm abs.
