Membrane solubilization by a hydrophobic polyelectrolyte: surface activity and membrane binding

Hydrophobic Polyelectrolyte: Surface Activity and Membrane Binding

We have previously observed that the hydrophobic polyeleclyte poly(2-ethylacryfic aad) solubilizes lipid mnembranes in a pH-dependent manner, and we have explited this phenomenon to prepare lipid vesicles that release their contents in response to pH, light, or glucose (Thomas, J. L., and D. A. Tirrell. Acc. Chem. Res. 25:336-342, 1992.) The physical basis for the interacfion between poly(2-eth...

A COMPARATIW STUDY ON THE BINDING OF HEXOKINASE TO THE OUTER MITOCHONDRIAL MEMBRANE AND A HYDROPHOBIC MATRIX

Solubilization and characterization of a platelet membrane ADP-binding protein.

Previous studies have shown that platelet membranes bind radiolabeled ADP and have nucleoside diphosphokinase activity which transforms added ADP to ATP. In order to further characterize these reactions, the ADP-binding and nucleoside diphosphokinase activity of purified platelet membranes were solubilized by freeze-thaw injury followed by extraction with isotonic buffered saline. Up to 80% of ...

Hydophilic polypropylene microporous membrane for using in a membrane bioreactor system and optimization of preparation conditions by response surface methodology

In this study, the response surface methodology (RSM) based on the central composite design (CCD) was used to optimize the preparation condition of polypropylene-grafted maleic anhydride (PP-g-MA) microporous membrane by thermally-induced phase separation (TIPS) method. A mixture of dibutyl phthalate (DBP) and dioctyl phthalate (DOP) was used as diluent. The effect of polymer composition and qu...

A Facile Approach of Thin Film Coating Consisted of Hydrophobic Titanium Dioxide over Polypropylene Membrane for Membrane Distillation

In this work, the hydrophobic modification of TiO2 nanoparticles (HTiO2) was carried out by reacting with dodecylphosphonic acid (DDPA) and hexylamine solution. A facile approach of the self-assembly technique was used for the coating of hydrophobic HTiO2 layer over the microporous polypropylene (PP) membrane. The self-assembled layer was formed between the interface of trimesoyl chloride (TMC)...
