Nanofibers were prepared from polycaprolactone, polylactide and polyvinyl alcohol using Nanospider(TM) technology. Polyethylene glycols with molecular weights of 2 000, 6 000, 10 000 and 20 000 g/mol, which can be used to moderate the release profile of incorporated pharmacologically active compounds, served as model molecules. They were terminated by aromatic isocyanate and incorporated into t...

This review describes protein purifications from cell culture medium or cell-lysate by high speed counter-current chromatography using the cross-axis coil planet centrifuge. Purifications were performed using aqueous two phase systems composed of polyethylene glycols and dextrans.
Bioconsequences Section, Unilever Research Port Sunlight Laboratory, Port Sunlight, Wirral, Merseyside L62 4XN, U.K. Polyethylene glycols are an important group of polymers used in the manufacture of explosives, cosmetics and pharmaceuticals. In addition, the polyoxyethylene group is the hydrophilic head group of non-ionic surfactants such as the alcohol ethoxylates used in detergent formulatio...
