Binding of Sodium Dodecyl Sulfate to Bovine Serum Albumin ...

Sep 22, 1998  One of the main difficulties in studying the interaction of protein and a surfactant at an interface is to establish the structural distributions of each component in the mixed layer. We demonstrate in this work that the distributions of the surfactant, protein, and water adsorbed at the hydrophilic solid/aqueous solution interface can be separately and unambiguously determined by using ...

Sodium dodecyl sulphate-treated proteins as ligands in ELISA

However, denaturation and solubilization with 2% sodium dodecyl sulphate (SDS) renders these proteins suitable ligands for ELISA. In quantitative ELISA using polyclonal antibodies as primary antibody, comparable results were obtained with native and SDS-denatured protein ligands. The binding of the antibodies to the SDS-treated ligands was ...

Sodium dodecyl sulfate-resistant complexes of Alzheimer's ...

Previous studies demonstrated sodium dodecyl sulfate (SDS)-resistant binding of apoE to the main component of Alzheimer's amyloid-A beta and modulation of A beta aggregation by apoE in vitro. To more closely characterize apoE-A beta interactions, we have studied the binding of thrombolytic fragments of apoE3 to A beta in vitro by using SDS ...

Detergent binding explains anomalous SDS-PAGE migration of ...

Feb 10, 2009  Migration on sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) that does not correlate with formula molecular weights, termed “gel shifting,” appears to be common for membrane proteins but has yet to be conclusively explained. In the present work, we investigate the anomalous gel mobility of helical membrane proteins using a library of wild-type and mutant helix-loop ...

Binding of Deoxycholate, Triton X-100, Sodium Dodecyl ...

Binding measurements using the separated tryptic fragments show that deoxycholate and Triton X-100 (both nondenaturing detergents) bind to the hydrophobic fragment to the same extent as to intact cytochrome b 5, and not at all to the polar fragment. Sodium dodecyl sulfate (a denaturing detergent) is bound to both tryptic fragments, but 70% of ...

Jun 10, 2009  The Kuhn statistical segment length, A, was determined for the sodium dodecyl sulphate (SDS)–protein complexes in two binding levels of SDS adsorbed onto the protein. These complexes are treated as random coil polymers. For the SDS–protein complex of binding level 1.4 g SDS per gram of protein, the value of A was found equal to 76 and 37 Å in 0.01 and 0.1 M ionic strength,

A wide variety of proteins have been shown to bind identical amounts of an amphiphile, sodium dodecyl sulfate, on a gram per gram basis at monomer equilibrium concentrations above 0.5 mM. The binding is independent of ionic strength and primarily hydrophobic in nature. Only the monomeric form of the amphiphile binds to proteins, not the micellar form.
