  • Patent number: 11932673
    Abstract: Binding members for sodium channel Nav1.7 and their use in medicine including for treatment of pain or epilepsy. Binding members comprise a fusion protein containing a Nav1.7-binding peptide, e.g., venom toxin peptide or knottin (“donor diversity scaffold domain”) inserted within an antibody variable domain (“recipient diversity scaffold domain”), and a partner domain (e.g., antibody variable domain), optionally wherein the partner domain enhances specificity of binding to Nav1.7 over other sodium channels.

  • Patent number: 11926818
    Abstract: The invention relates to methods of producing eukaryotic cell libraries encoding a repertoire of binding molecules (“binders”), wherein the methods use a site-specific nuclease for targeted cleavage of cellular DNA to enhance site-specific integration of binder genes through endogenous cellular repair mechanisms. Populations of eukaryotic cells are produced in which a repertoire of genes encoding binders are integrated into a desired locus in cellular DNA (e.g., a genomic locus) allowing expression of the encoded binding molecule, thereby creating a population of cells expressing different binders.

  • Publication number: 20230212288
    Abstract: The invention relates to the field of immunology and biotechnology, and also to the creation of novel effective high-molecular compounds having therapeutic properties. Variants of amino acid sequences of complementarity-determining regions (CDR) of antigen-binding fragments of a protein molecule specific to human cell CD3 receptors are proposed. The proposed CDR can be used for engineering various antigen-binding molecules, one of the essential function of which is a specific interaction with CD3-bearing cells. Bispecific molecules that specifically bind to human cell CD3 and CD19 receptors were engineered by means of the inclusion of said CDR in the composition of an antibody-like molecule intrinsically binding to the CD19 receptor.

  • Patent number: 11499150
    Abstract: Use of the surface presentation level of binders (e.g., antibodies, receptors) on cultured higher eukaryotic cells in vitro as a predictive indicator of developability characteristics, e.g., solubility, of the binders. Display libraries of higher eukaryotic cells, e.g., mammalian cells, adapted for use in screening surface-displayed binders for developability and affinity of target binding. High-throughput screening of display libraries with in-built selection for developability including binder solubility, capability to be formulated at high concentrations, low propensity for non-specific binding, and half-life. Enrichment of populations of binders for developability characteristics and/or other qualities such as target binding and affinity, by controlling cell surface presentation of binders from an inducible promoter operably linked to binder-encoding DNA.

  • Publication number: 20120129710
    Abstract: A member of a specific binding pair (sbp) is identified by expressing DNA encoding a genetically diverse population of such sbp members in recombinant host cells in which the sbp members are displayed in functional form at the surface of a secreted recombinant genetic display package (rgdp) containing DNA encoding the sbp member or a polypeptide component thereof, by virtue of the sbp member or a polypeptide component thereof being expressed as a fusion with a capsid component of the rgdp. The displayed sbps may be selected by affinity with a complementary sbp member, and the DNA recovered from selected rgdps for expression of the selected sbp members. Antibody sbp members may be thus obtained, with the different chains thereof expressed, one fused to the capsid component and the other in free form for association with the fusion partner polypeptide. A phagemid may be used as an expression vector, with said capsid fusion helping to package the phagemid DNA.
