Isolation and characterization of muscle membranes using surface-specific labels.
Membranes were purified from rat muscle by a differential centrifugation method that avoids the use of salt extraction or incubations at elevated temperature. Three populations of membrane-limited vesicles were defined having average densities of 1.112 (fraction I), 1.141 (fraction II), and 1.158 (fraction III) g/ml in a continuous sucrose gradient. Lactoperoxidase-catalyzed iodination of intac...

Isolation and Characterization of Subcellular Membranes
A method is described for the isolation of subcellular membranes of Entamoeba invadens. Plasma membranes were obtained by rate centrifugation followed by isopycnic centrifugation on a sucrose gradient. Intact phagolysosomes floated in a 10% sucrose solution providing a simple technique for isolation. Phagolysosomal membranes were collected by isopycnic centrifugation, after lysis of the phagoly...
متن کاملThe Isolation of Organic Compounds using Organophilic Pervaporation Membranes
Organophilic membranes provide a method of recovering organic compounds by pervaporation, which exploits the selective transport of the organic phase. The main application is in the extraction of bio-alcohols from aqueous solution. The effect of membrane composition on performance in transporting alcohols and not water at improved rates is the focus of this review. In th...
متن کاملPreparation and characterization of nano-porous Polyacrylonitrile (PAN) membranes with hydrophilic surface
Polyacrylonitrile (PAN) membranes with nano-porous surface and high hydrophilicity were fabricated by addition of polyoxyethylene (40) nonylphenyl ether (IGEPAL) as an additive in the casting solution. The membranes were prepared from PAN/IGEPAL/1-Methyl-2-pyrrolidone (NMP) via phase inversion induced by immersion precipitation technique. Pure water was used as coagulation medium. The effects o...
