    摘要: The invention relates to sulphated polysaccharides which have the general structure of the constituent polysaccharides of heparin and which have a molecular weight of less than 8000 Daltons, comprising two antithrombin III-binding hexasaccharide sequences corresponding to formula (I) in which: R1 represents an OH group when the hexasaccharide of formula (I) is located at the reducing end of the polysaccharide, or else R1 represents a bond with another saccharide unit of said polysaccharide; R2 represents a hydrogen atom when the hexasaccharide of formula (I) is located at the non-reducing end of the polysaccharide, in which case the bond between carbon atoms 4 and 5 of the first saccharide unit of said hexasaccharide is a double bond, or else R2 represents a bond with another saccharide unit of said polysaccharide, in which case the bond between carbon atoms 4 and 5 of the first saccharide unit is a single bond. Preparation thereof, use thereof as antithrombotic medicaments, and also use thereof in a method for analyzing a sample of a heparin derivative.

    摘要: A protein structure capable of selective interaction with an organic target is provided. The protein structure is a polymer comprising as a repeating structural unit a recombinant fusion protein that is capable of selective interaction with the organic target. The fusion protein is comprising the moieties B, REP and CT, and optionally NT. B is a non-spidroin moiety of more than 30 amino acid residues, which provides the capacity of selective interaction with the organic target. REP is a moiety of from 70 to 300 amino acid residues and is derived from the repetitive fragment of a spider silk protein. CT is a moiety of from 70 to 120 amino acid residues and is derived from the C-terminal fragment of a spider silk protein. NT is an optional moiety of from 100 to 160 amino acid residues and is derived from the N-terminal fragment of a spider silk protein. The fusion protein and protein structure thereof is useful as an affinity medium and a cell scaffold material.
