Description and Uses
Lithium dodecyl sulfate (LDS) is an anionic detergent and surfactant that is frequently used in electrophoresis and chromatography. LDS may be substituted for sodium dodecyl sulfate (SDS) in electrophoresis under cold conditions. The use of LDS in micellar electrokinetic chromatography has been extensively studied. A report has been published on the partition equilibria of LDS between water and bilayer membranes. LDS has been utilized in protein electrophoresis and proteomics studies. The three-dimensional structure of the amyloid β-protein fragment 25-35 has been investigated in LDS micelles by two-dimensional 1HNMR. LDS has been used to induce changes in protein conformation.
Anionic detergent that may be used in place of SDS for electrophoresis in cold conditions.
