    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.

    摘要: The present invention relates to a method for detecting the presence or non-presence of an endotoxin, characterized in that an OmpT protein is brought into contact with a sample suspected of containing an endotoxin and the protease activity of the OmpT protein is assayed. It also relates to a method for detecting early onset of septicaemia using the inventive method and a kit for performing the method.

    摘要: The present invention relates to modified polypeptide derivatives of the B domain or Z domain of staphylococcal protein A (SPA). The derivatives contain amino acid substitutions that result in the ability of the B domain or Z domain to interact with at least one domain of a human Factor VIII protein, without substantially disrupting the structure and stability of the B domain or Z domain.
