Remark


Applications of Sodium Dodecyl Sulfate


  • It is used for solubilization and protein denaturation, suitable for denaturing applications in PAGE (Polyacrylamide Gel Electrophoresis). Most proteins bind to SDS at a ratio of 1.4 g SDS per gram of protein. In relation to the overall negative charge carried by the bound SDS, the intrinsic charge of the protein is almost negligible. The mass-to-charge ratio is roughly the same for each protein and migration in the gel is based on molecular size. Anionic detergent.


Packaging of Sodium Dodecyl Sulfate


  • It is packed in polyethylene bags lined with plastic woven bags, with a net weight of 25 kg per bag.


Storage and Transportation of Sodium Dodecyl Sulfate


  • It should be stored in a dry, well-ventilated, and clean warehouse, handled with care to avoid moisture and heat. During transportation, it should be protected from rain and moisture. It should be stored separately from toxic substances.
