Lithium Dodecyl Sulfate (LDS) is a chemical compound with significant applications in the life sciences, particularly in molecular biology and protein research. It is a type of anionic detergent and belongs to the class of alkyl sulfates.

LDS is commonly used as a surfactant and denaturing agent in various laboratory techniques. It is widely used in protein electrophoresis, particularly in sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE).

LDS helps solubilize proteins, denature them, and impart a negative charge proportional to their size, allowing for separation based on molecular weight. It is also used in membrane protein studies and as a component in protein extraction buffers. It aids in the solubilization and extraction of membrane proteins, facilitating their analysis and characterization.

Additionally, LDS is utilized in the preparation of protein samples for mass spectrometry analysis. It helps to enhance protein solubility, reduce protein-protein interactions, and promote efficient digestion of proteins by proteases.
