    摘要: A peptide having a sequence corresponding to an antigenic site in the protein exoenzyme S which is antigenically similar to a C-terminal portion of the Pseusdomonas aeruginosa pilin protein is disclosed. The peptide is cross-reactive with surface peptides present in certain bacterial and fungal microorganisms, and is effective in inhibiting binding of such organisms to target epithelial cells. The peptide may also be employed in a vaccine composition, for producing immunity against such cross-reactive microorganisms.

    摘要: The present invention relates to a composition, device and method for preventing or inhibiting biofilm formation on biotic or abiotic surfaces. The composition comprises a peptide based on the C-terminal receptor binding domain of Pseudomonas aeruginosa type IV pilin, which binds to an abiotic surface (e.g., steel, plastic) with high affinity and prevents binding of a variety of P. aeruginosa strains to the surface. The inventive composition represents a non-toxic inhibitor for biofilm formation, particularly on an abiotic surface, which is responsible for a large number of problematic diseases and massive economic losses. The inventive method is useful as a safe and environmentally friendly means of modifying a surface of a variety of biomedical, nanotechnological, and biotechnological devices or articles.

    摘要: A biosensor apparatus for detecting a binding event between a ligand and receptor. The apparatus includes a biosensor surface and surface-bound two-subunit heterodimer complexes composed of first and second, preferably oppositely charged peptides that together form an &agr;-helical coiled-coil heterodimer. The-first peptide is attached to the biosensor surface, and the second peptide carries the ligand, accessible for binding by a ligand-binding agent. Binding of anti-ligand binding agent to the surface-bound ligand is detected by a suitable detector. A ligand-specific biosensor surface can be readily prepared from a universal template containing the first charged peptide, by addition of a selected ligand attached to the second peptide.
