  • Publication number: 20150152406
    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.

  • Publication number: 20150072412
    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. The methods disclosed herein allow the expression of diverse collections of binding proteins from at least one vector construct, which optionally can give rise to collections of diverse binding proteins upon transfer and expression into vertebrate host cells in situ.

  • Publication number: 20110059056
    Abstract: The present invention generally relates to the fields of genetic engineering and antibody production. In particular, it relates to the generation of genetically modified vertebrate precursor lymphocytes that have the potential to differentiate into more mature lymphoid lineage cells, and to the use thereof for the production of any heterologous antibody or binding protein.
