  • Publication number: 20140227786
    Abstract: The present invention relates to methods of host cell transduction utilising ecotropic retroviral vector particles. The retroviral vector particle may comprise an envelope of Friend murine leukaemia virus, in particular the envelope encoded by molecular clone PVC-211 and the host cell may be engineered to recombinantly express the Rec1 receptor. The retroviral vector particles and methods of the invention can be used to introduce expressible polynucleotide sequences of interest into host cells with high efficiency. This results in protein production methods with higher yield (mg/L) and a reduction in manufacturing costs that could be used in a range of applications including for example, the production of therapeutic proteins, vaccines and antibodies.

  • Patent number: 8748353
    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.
