Sodium dodecyl sulfate
Sodium Dodecyl Sulfate
Sodium dodecyl sulfate (pronunciation: SO-dee-um do-DE-sil sul-fate), also known as SDS or sodium lauryl sulfate, is an anionic surfactant commonly used in laboratory procedures. The term "sodium dodecyl sulfate" is derived from the compound's chemical structure, which includes a chain of 12 carbon atoms (dodecyl) attached to a sulfate group.
Usage
Sodium dodecyl sulfate is widely used in biological research as a detergent to break up and denature proteins during SDS-PAGE, a common method of protein separation. It is also used in DNA extraction procedures to lyse cells and denature proteins, allowing for the DNA to be isolated.
Safety
While sodium dodecyl sulfate is generally safe for laboratory use, it can be irritating to the skin and eyes. It is recommended to use appropriate personal protective equipment when handling SDS.
