  • 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.

  • 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: 20210179677
    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.
