Abstract: The present invention provides the means for producing libraries of peptide structures for drug screening applications that are capable of folding or assuming their native conformations independently of artificial scaffolds or flanking sequences in the proteins from which they are derived. The libraries can be highly diverse such that they are representative of the repertoire of protein structures existing in nature. The libraries can also be non-redundant or normalized such that the bias towards specific structures existing in source data sets and/or in nature is/are removed. In a particularly preferred embodiment, the present invention provides 30,000 independent fold structures produced by this method. The present invention also provides computer-readable media and systems comprising structural data in relation to the peptide libraries, and methods for displaying and screening the libraries.

Abstract: The present invention provides a method for identifying a modulator or mediator of a biological activity, which activity includes antigenicity and or immunogenicity, said method comprising the step of: (i) producing a gene fragment expression library derived from defined nucleotide sequence fragments; and (ii) assaying the expression library for at least an amino acid sequence derived from step (i) for a biological activity wherein that activity is different from any activity the amino acid sequence may have in its native environment.

Abstract: The present invention provides compositions comprising peptidyl inhibitors of CD40L-dependent signalling that are not derived from a natural binding partner of CD40L such as CD40, or from a native CD40-CD40L interface. More particularly, the peptidyl inhibitors of the present invention are derived from natural sources that do not express CD40-CD40L costimulatory pathways. The invention also provides synthetic derivatives and analogs of the peptidyl inhibitors having enhanced binding affinity for CD40L or enhanced inhibitory activity relative to their parent molecules.

Abstract: A one-way valve (10) is disclosed which comprises a body portion (12) defining a passage through which fluid is able to pass during use, a support member (22) disposed in the passage, a seat member (28) disposed in the passage and provided with at least one aperture (32), a shaft (24) extending between the support member (22) and the seat member (28) and a membrane (26) disposed on the shaft (24) such that the membrane (26) is rotatable relative to the shaft (24). The seat member (28) cooperates with the membrane (26) such that a first predetermined pressure differential across the membrane (26) causes the membrane to cover the at least one aperture (32) and thereby prevent fluid flow past the seat member (28), and such that a second predetermined pressure differential of opposite polarity to the first predetermined pressure differential causes the membrane (26) to not cover the at least one aperture (32) and thereby permit fluid flow past the seat member (28).

Abstract: The present invention provides improved reverse hybrid assay methods for identifying amino acid residues within a protein that are required for its interaction or physical association with another protein, wherein disruption of an interaction between a protein of interest and its binding partner protein is assayed for a library of mutations of said protein of interest, and maintenance of an interaction between the protein of interest and another binding partner is assayed simultaneously in a single step, thereby reducing the incidence of uninformative mutations in the protein of interest that are detected.
