    摘要: The present invention relates to a filamentous phage display method wherein the polypeptides of interest displayed on the phage particle are cotranslationally translocated across the cytoplasmic membrane of Gram-negative bacteria based on the signal recognition particle pathway. This method is particularly suitable for polypeptides, which are known to be difficult to display on phages, and for proteins of cDNA libraries and other combinatorial libraries, in particular when derived from very fast folding, stable protein scaffolds. The invention further relates to phage or phagemid vectors useful in the method comprising a gene construct coding for a fusion polypeptide comprising the polypeptide to be displayed on the phage particle and an N-terminal signal sequence promoting cotranslational translocation.

    摘要: The invention relates to collections of target-specific designed binding proteins based on armadillo repeat proteins, and to a method of generating them. Designed armadillo repeat proteins are based on consensus sequences of single armadillo repeat units. These repeat proteins can be used as scaffolds for peptide recognition. Such a scaffold provides a binding mode that is in principle the same for every small recognizable unit, e.g. an amino acid or dipeptide, allowing a precise and modular recognition of a peptide in extended conformation. The method allows to generate a series of modules recognizing these simple units, and to combine such building blocks to create a binding site for any desired peptide target without performing additional selections.

    摘要: The present invention relates to synthetic DNA sequences which encode one or more collections of homologous proteins/(poly)peptides, and methods for generating and applying libraries of these DNA sequences. In particular, the invention relates to the preparation of a library of human-derived antibody genes by the use of synthetic consensus sequences which cover the structural repertoire of antibodies encoded in the human genome. Furthermore, the invention relates to the use of a single consensus antibody gene as a universal framework for highly diverse antibody libraries.

    摘要: The present invention relates to the modification of immunoglobulin superfamily (IgSF) domains, IgSF fragments and fusion proteins thereof, especially to the modification of antibody derivatives, so as to improve their solubility, and hence the yield, and ease of handling. The inventors have found that this can be achieved by making the region which comprised the interface with domains adjoined to said IgSF domain in a larger fragment or a full IgSF protein, and which becomes exposed in the IgSF domain, more hydrophilic by modification. The present invention describes DNA sequences encoding modified IgSF domains or fragments and fusion proteins thereof, vectors and hosts containing these DNA sequences, IgSF domains or fragments or fusion proteins obtainable by expressing said DNA sequences in suitable expression systems, and a method for modifying IgSF domains, so as to improve their solubility, expressibility and ease of handling.
