摘要:
A modified human TNFα molecule is capable of raising neutralizing antibodies towards unmodified human TNFα following administration of the modified TNFα to a human host, wherein one or more peptide fragments of the human TNFα molecule has been substituted by one or more peptides containing immunodominant T cell epitopes or a truncated form of the molecule containing the immunodominant epitope and one or both flanking regions of the human TNFα-molecule containing at least one TNFα B cell epitope, wherein the substitution introduces a substantial change in the amino acid sequence of any one of the strands of the front β-sheet, in any one of the connecting loops, or in any one of the B′, I, or D strands of the back β-sheet.

A method of modifying the binding properties on a surface of a solid phase on which there are nucleophilic groups, which is characterized in that the surface is treated with a solution of an activated polysaccharide; a method of immobilizing a chemical compound to a solid phase on which there are immobilized activated polysaccharides, whereby the chemical compound is contacted with the surface of the solid phase the binding properties of which are modified by the method according to the invention; an article which is characterized in that to the surface thereof an activated polysaccharide is fixated, such as activated dextran or activated agarose, and use of this article for use in solid phase reactions, in solid phase assay, solid phase peptide synthesis, solid phase nucleotide synthesis, solid phase enzyme processing, and joining of biological surfaces.
摘要:
A method of preparing a tresyl-activated dextran is disclosed in which an aqueous solution of dissolved dextran is reacted with a tresylating agent in a hexamethylphosphoric triamide and/or N-methyl pyrrolidinone solvent, and the formed tresyl-activated dextran is recovered. A method of immobilizing a chemical compound to the surface of a solid phase having nucleophilic groups covalently bound or non-covalently bound is also disclosed, the method involving treating the surface with a solution of tresyl-activated dextran prepared as described above, and contacting the chemical compound with the treated surface. An article is also disclosed wherein tresy-activated dextran prepared as described above is fixed covalently to its surface.
摘要:
A method for modifying the surface of a solid polymer wherein the polymer surface is exposed to an aqueous solution containing a two-ring heterocyclic compound that is described in more detail herein. The polymer and the two-ring heterocyclic compound are irradiated with electromagnetic radiation having a wavelength ranging from about 10 nm to about 400 nm to photochemically immobilize the two-ring heterocyclic compound to the polymer.
摘要:
The present invention describes methods for identification of molecules expressed at a different level on the cell surface of cancer cells compared to non-malignant cells and methods of identification of cancer specific promoters to be used singly or in combination for delivery and expression of therapeutic genes for treatment of cancer. The invention furthermore describes targeting complexes targeted to cell surface molecules identified by the methods of the invention. In embodiments of the invention said targeting complexes comprise the promoters identified by the methods of the invention. In addition the invention describes methods of identifying binding partners for the cell surface molecules and the binding partners per se. Methods of treatment using the targeting complexes and uses of the targeting complexes for the preparation of a medicament arc also disclosed by the invention. Furthermore, the invention describes uses of the cell surface molecules or fragments thereof for preparation of vaccines.
