Glutathione S-transferase (GST) is widely used to prepare and purify GSTtagged fusion proteins. Although GST improves protein solubility, detergents must often be used to achieve protein solubilization from bacterial lysates. However, purification of GST by affinity chromatography cannot be achieved in the presence of even low concentrations of the detergent sodium dodecyl sulfate (SDS). Here w...

Gold nanoparticles prepared by chemical reduction in sodium dodecyl sulfate (SDS) solution are size-controlled with the addition of pyrene. Micellar electrokinetic capillary chromatography (MEKC) is applied to the system to examine the size and polydispersity of gold nanoparticles and to show that pyrene has the extraordinary effect in decreasing the size and narrowing the dispersity of gold na...

The influence of the small ionic surfactant sodium dodecyl sulfate (SDS) on the evaporation of drying colloidal droplets is quantitatively investigated. The addition of SDS leads to a significantly more uniform deposition of colloidal particles after evaporation (i.e., the so-called "coffee-ring effect" is dramatically altered). We understand this phenomenon in the context of circulating radial...

The effect of the presence sodium dodecyl sulfate (SDS) on denaturation bovine serum albumin (BSA) has been studied using 36 m small-angle neutron scattering (SANS) BATAN spectrometer (SMARTer). data reduction used Graphical Reduction and Analysis SANS Program (GRASP) software, fitting process IGOR software. was identified by observing changes BSA globular structure. experimental results showed...

There is little understanding of how anionic surfactants affect the transport carbon dots (CDs) nanoparticles in soil. In this study, mobility characteristics CDs soil columns with sodium dodecyl sulfate (SDS, a model surfactant) under various conditions were investigated. The results showed that presence SDS enhanced at pH 7.0 when Na + was main background electrolyte. increased electrostatic ...

The main factor affecting the economics of foam-assisted water alternative gas (FAWAG) process is the loss of foaming agent by adsorption onto reservoir rocks. In this study, the effects of phases, surfactant concentration, salinity, adsorbents, and sacrificial agent on adsorption density were investigated by special adsorption experiments. Moreover, a series of FAWAG tests were performed to ex...

Two strains of Staphylococcus aureus (PC1 and 196E), when grown in medium containing 0.002% sodium dodecyl sulfate (SDS), showed from 96.1 to 100% loss of the ability to produce penicillinase. Resistance to cadmium and zinc was lost concomitantly with the ability to produce penicillinase. A comparison of the rate of curing by SDS with the curing effects exerted by elevated temperature and ethid...

Abstract In this paper, a comparative study was conducted on the extraction effects of six agents for collagen-based mural painting binders. These were used to extract residual proteins in non-aged and thermal aged samples. The protein efficiencies different extracting quantitatively determined by bicinchoninic acid (BCA) method, then processed multivariate analysis variance (MANOVA). impact pr...

Methane hydrate applications in gas storage and desalination have attracted increasing attention recent years. In the present work, effect of isopentane (IP), sodium dodecyl sulfate (SDS), IP/SDS blends as promoters on methane formation kinetics, terms pressure–temperature (P-T) profile, uptake, induction time (HIT), water-to-hydrate conversion ratio (WHCR), were studied for distilled water sea...
