23 Sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE) is a universally 24 used method for determining approximate molecular weight (MW) in protein research. 25 Migration of protein that does not correlate with formula MW, termed " gel shifting " appears 26 to be common for histidine-rich proteins but not yet studied in detail. We investigated " gel 27

Solubilization of the human erythrocyte membrane by seven detergents is described. Components released into the supernatant or retained in the residue were identified by sodium dodecyl sulphate/polyacrylamide-gel electrophoresis. Two non-ionic detergents exhibiting little u.v. absorption were more efficient than u.v.-absorbing Triton X-100. Evidence is presented of an interchange between protei...

The surface proteins of dividing and non-dividing subpopulations of rat and mouse thymocytes have been labelled by using a new method of radioiodination. Sodium dodecyl sulphate/polyacrylamide-gel electrophoresis and autoradiography of the labelled proteins shows distinct differences in labelling between the mouse and rat cells and also, in the case of the rat, between the dividing and non-divi...

A series of atomistic molecular dynamics simulations were performed for investigating the interactions between three different testosterone-based compounds (testosterone (T), testosterone propionate (TP) and testosterone enanthate (TE)) and sodium dodecyl sulphate (SDS) and ammonium dodecyl sulphate (ADS) monolayers, which vary only in the sodium or ammonium counterions used to neutralise the s...

Nano micelles of sodium dodecyl sulphate in water were prepared as local lipophilic media for the organisation of interacting chromophores. Such arrangements were controlled by peripheric substituents to operate either as isolated chromophores or as skew oriented pairs where H-type transitions cause hysochromic absorption and J-type transitions bathochromic fluorescence. As a consequence, large...

n-Dodecyl-beta-D-maltoside was used as a detergent to solubilize the ammonium sulphate precipitate of chloroplast F(O)F(1)-ATP synthase, which was purified further by dye-ligand chromatography. Upon reconstitution of the purified protein complex into phosphatidylcholine/phosphatidic acid liposomes, ATP synthesis, driven by an artificial DeltapH/Deltapsi, was observed. The highest activity was a...

Copper oxide nanoparticles were anchored on sodium dodecyl sulphate (SDS)-functionalized macroporous carbon by utilizing the supramolecular self-assembly of SDS acting as a soft template. The as-prepared composite provides new features of electrocatalytic activities and may hold great promise for the design of environmental sensors.

Fatty acid synthetase purified from the mammary gland of the rabbit has a mol. wt. of 968000 as determined by gel filtration. The enzyme gave one band, corresponding to a mol.wt. of approx. 35000, on polyacrylamide-gel electrophoresis in the presence of sodium dodecyl sulphate and phenylmethanesulphonyl fluoride.
