the interaction of sodium n-dodecyl sulphate (sds) with histones in phosphate buffer ph 6.4 has been studied spectroscopically and by equilibrium dialysis. the enthalpies of interaction and the spectroscopic data suggest different structural stability for histones-sds interaction. the linear relation between enthaly and absorbtion was determined by the equation of m= , where m is the stability ...

Maltase/glucoamylase from the rat intestinal brush-border membrane was solubilized by homogenization of the intestinal mucosa in buffer containing 0.5% Triton X-100. After removal of the detergent with butan-1-ol, the enzyme was purified by chromatography on Sepharose 4B and DEAE-cellulose. The final specific activity was 70.3 units/mg of protein in six preparations, comparing favourably with t...

The effects of sodium n-dodecyl sulphate (SDS) on the structure of histone HI has been studied by a combination of e:quilibrium dialysis, U.V. spectroscopy ; polyacrylamide gel electrophoresis, protein titration and viscometery techniques using, 2.5 mM phosphate buffer, pH 6.4. The interaction of H, and SDS in contrast tomanyothel-protein-SDS interactions is organized between V 40 to 70. A...

H]glucosamine has been used to label metabolically keratinocyte cell-surface glycoconjugates. The major labelled bands identified on sodium dodecyl sulphate/polyacrylamide gels had apparent molecular weights of greater than 250000, and 150000-80000. Most of these components were trypsin-sensitive, indicating that the label was protein-bound. Some of the labelled components were shown to be prot...

Anatase nanoparticles synthesized by the sol-gel method were surface-functionalized with long alkyl chain coupling agents as compatibilizers for a nonpolar environment, containing different anchor groups for surface interaction namely phosphonate (dodecyl phosphonate), carboxylate (dodecanoic acid), sulfate (sodium dodecyl sulphate), and amine (dodecyl amine). It was shown that the surface of t...

A Study was made on the interaction between histon H1 and sodium n-dodecyl sulphate (SDS) in the presence of sodium arsenate inside a phosphate buffer of pH 6.4, using spectroscopy and equilibrium dialysis at 27 °C. The binding data has been used to obtain the gibbs free energy in terms of a theoretical model based on the Wyman binding potential. The binding data hs been analysed...

The capture, storage and utilization of CO2 through hydrate-related technology is a promising approach to addressing the global warming issue. Dissociation required after transportation gas in form self-preserving hydrate. In order investigate dissociation behaviors as self-preservation effect removed, hydrates were frozen, then was removed uniform heating. An evident dependence hydrate duratio...
