    Abstract: The present invention relates to an enzyme sensor for measuring the concentration or activity of an analyte of a test fluid. The sensor has at least one enzyme layer comprising an immobilised enzyme for which the analyte is a substrate. The immobilised enzyme is obtained by formation of one or more covalent link(s), optionally by using a cross-linking agent, between the enzyme and at least one type of macromolecule in the presence of a competitive inhibitor for said enzyme. The present invention also relates to a membrane for an enzyme sensor. Furthermore, the invention relates to a method for stabilising the enzymatic activity of an enzyme sensor.

    Abstract: In accordance with the present invention, there are provided rapidly crosslinkable polypeptides which are obtained upon introduction of unsaturated group(s) into the polypeptide via linkage to amino acid residues on the polypeptide directly through one of three types of linkages, namely, an amide linkage, an ester linkage, or a thioester linkage. Each of these linkages are obtainable in a single step by use of a single derivatizing agent, acrylic anhydride. Also provided are methods for preparing such modified polypeptides and various uses therefor. It has unexpectedly been found that proteins with the above-described chemical modifications have the ability to rapidly crosslink to themselves under suitable conditions. This cross-linking occurs in the absence of any external crosslinking agents (indeed, in the absence of any extraneous agents), resulting in the formation of a solid gel material. Solid crosslinked gels are formed in seconds, starting from a freely flowing solution of polypeptide. Applications of such materials are broad ranging, including the encapsulation of living cells, the encapsulation of biologically active materials, the in situ formation of degradable gels, the formation of wound dressings, the prevention of post-surgical adhesions, gene delivery, drug targetting, as a microcarrier for cultrure of living cells, and the like.

    Abstract translation: 根据本发明,提供了快速可交联的多肽,其通过直接通过三种类型的键之一连接到多肽上的氨基酸残基而将不饱和基团引入到多肽中,即三酰胺键 ,酯键或硫酯键。 这些连接中的每一个可以通过使用单一衍生剂丙烯酸酐在一个步骤中获得。 还提供了制备这种修饰的多肽及其各种用途的方法。 意外地发现具有上述化学修饰的蛋白质具有在合适条件下快速与其自身交联的能力。 这种交联发生在没有任何外部交联剂的情况下(实际上,在没有任何外来物质的情况下),导致形成固体凝胶材料。 固体交联凝胶在几秒钟内形成,自由流动的多肽溶液开始。 这些材料的应用范围广泛,包括活细胞的包封,生物活性物质的包封,可降解凝胶的原位形成,伤口敷料的形成,预防手术后粘连,基因递送,药物靶向, 作为用于培养活细胞的微载体等。

    Abstract: Apparatus for catalysis in multiphase reaction systems is provided in which catalysts are confined within various membranes without the use of covalent coupling. Confinement of the catalysts is achieved by a combination of a small-pore skin on one side of the membrane and the use of a solvent in which the catalysts are not appreciably soluble on the other. Methods are also provided for the preparation of such apparatus and for their regeneration by incorporation of fresh catalyst.
