  • Patent number: 11661676
    Abstract: The invention relates to a method for selecting a sequence set from a library of expressed nucleic acid sequences, wherein cells are provided, each cell comprises an expressed nucleic acid sequence expressed as a target protein. The cells are encapsulated by treating them with a cationic polysaccharide and subsequently treating them with an anionic polysaccharide, yielding encapsulated cells, perforating the membrane of the encapsulated cells, yielding solubilized compartments, contacting them with a ligand to said target protein, the ligand bearing a detectable label, and selecting a subset of solubilized compartments as a function of detectable label and isolating the expressed nucleic acid sequences from the selection as a selected sequence set.

  • Publication number: 20180003711
    Abstract: The invention relates to a method for selecting an expressed sequence from a library, comprising the following steps: Each of a plurality of eukaryotic cells comprising a cell wall comprises a nucleic acid sequence member of a library, which is expressed as a target membrane protein in said eukaryotic cells. The cell wall of the cells is permeabilized. The permeabilized cells are labeled with a ligand capable of binding to the target membrane protein. The ligand bears a detectable label. A subset of the labelled cells is selected as a function of detectable label present. Finally, an expressed nucleic acid sequence is isolated from said selection of cells in an isolation step.

  • Patent number: 9365629
    Abstract: 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.

  • Publication number: 20150057186
    Abstract: 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.
