Product Description:
Sodium dodecyl sulfate (SDS) is widely used in laboratories as a key component in SDS-PAGE (polyacrylamide gel electrophoresis) for separating proteins based on their molecular weight. It denatures proteins by breaking non-covalent bonds, allowing them to be uniformly coated with negative charges, ensuring separation is based solely on size.
In cleaning products, SDS acts as a surfactant, effectively removing dirt and grease by reducing surface tension and emulsifying oils. It is commonly found in detergents, shampoos, and toothpastes for its foaming and cleaning properties.
In the biotechnology and pharmaceutical industries, SDS is used to solubilize proteins and lipids, aiding in the study of their structure and function. It is also employed in DNA extraction procedures to break down cell membranes and release nucleic acids.
Additionally, SDS is utilized in industrial applications such as textile and leather processing, where it helps in wetting, emulsifying, and dispersing agents during manufacturing.
Its versatility and effectiveness make it a valuable chemical across various scientific, industrial, and household applications.
