  • Patent number: 10502745
    Abstract: The present invention discloses novel methods for the generation, expression and screening of diverse collections of binding proteins such as antibodies or fragments thereof in vertebrate host cells in vitro, for the identification and isolation of ligand- or antigen-specific binding proteins.

  • Publication number: 20190153092
    Abstract: The present invention relates to a human or humanized antibody, or an antibody-based binding protein, modified antibody format retaining target binding capacity, antibody derivative or fragment retaining target binding capacity, which targets Receptor tyrosine kinase-like orphan receptor-1 (ROR1). It further relates to bi- or multispecific antibodies, to Immunoligand-Drug Conjugates, to Chimeric Antigen Receptors and to T-cells comprising such Chimeric Antigen Receptors.

  • Publication number: 20190153433
    Abstract: The method disclosed herein describes a novel technology offering unparalleled efficiency, flexibility, utility and speed for the discovery and optimization of polypeptides having desired binding specificity and/or functionality, including antigen-binding molecules such as antibodies and fragments thereof, for desired functional and/or binding phenotypes. The novel method is based on transposable constructs and diverse DNA libraries cloned into transposable vectors and their transfection into host cells by concomitant transient expression of a functional transposase enzyme. This ensures an efficient, stable introduction of the transposon-based expression vectors into vertebrate host cells in one step, which can then be screened for a desired functional or binding phenotype of the expressed proteins, after which the relevant coding sequences for the expressed proteins, including antibodies and fragments thereof, can be identified by standard cloning and DNA sequencing techniques.
