摘要: The invention relates to hydrophilic membranes which are supplemented or treated with a non-ionic surfactant and processes for preparing such membranes. The membranes are particularly suitable for plasma separation or for haemodialysis and haemodiafiltration, but can also advantageously be used in other applications. Accordingly, the invention is further directed to the use of such membranes for plasma separation, plasma filtration, micro filtration, plasma therapy, haemodialysis and haemodiafiltration or cell filtration applications, respectively. The treated hydrophilic membranes show excellent biocompatibility, such as reduced platelet drop and decreased TAT levels.

The membranes comprise polyethersulfone and polyvinylpyrrolidone and are coated with hyaluronic acid or copolymers of 2-methacryloyloxyethyl phosphoryl choline and other vinyl polymerizable monomers. Processes for the preparation of these membranes, devices comprising these membranes, and the use of these membranes in hemodialysis, hemodiafiltration and hemofiltration of blood, as well as in bioprocessing, plasma fractionation and the preparation of protein solutions.

摘要: An immobilized enzyme comprises a solid support, an enzyme linked to the solid support and a spacer for coupling the enzyme to the solid support. A method for the production of immobilized enzymes comprises: providing a solid support having amino-functional groups coupled to the support surface; covalently coupling the amino-functional groups with a thermally labile radical initiator; and, contacting the support surface with a solution of polymerizable monomers. The polymerizable monomers comprise functional groups which do not take part in radical polymerization, under conditions where thermally initiated graft copolymerization of the monomers takes place, to form polymer chains on the surface of the support. If the polymer chains do not already comprise primary amino-functional groups, the method further comprises transforming the functional groups in the polymer chains into groups comprising primary amino-functional groups. The method further comprises coupling the enzyme to amino-functional groups of the polymer chains.
