  • Publication number: 20200267952
    Abstract: The invention relates, in one aspect, generally to novel concept of guided selection of antibody variable domains, combination and expression entirely in vivo. An application is to produce multivalent polypeptides. The present invention relates to multivalent (eg, multispecific) antibodies, antibody chains and polypeptides, as well as heavy chain-only antibodies (H2 antibodies) that are devoid of light chains. The invention further relates to the selection, maturation and production of these in vivo in non-human vertebrates and non-human vertebrate cells. To this end the invention also relates to such non-human vertebrates and cells. The invention also relates to the provision of means to produce and select heavy chain-only antibodies and heavy chains comprising variable domains that have undergone affinity maturation.

  • Publication number: 20190338274
    Abstract: The invention relates to an approach for introducing one or more desired insertions and/or deletions of known sizes into one or more predefined locations in a nucleic acid (eg, in a cell or organism genome). They developed techniques to do this either in a sequential fashion or by inserting a discrete DNA fragment of defined size into the genome precisely in a predefined location or carrying out a discrete deletion of a defined size at a precise location. The technique is based on the observation that DNA single-stranded breaks are preferentially repaired through the HDR pathway, and this reduces the chances of indels (eg, produced by NHEJ) in the present invention and thus is more efficient than prior art techniques. The invention also provides sequential insertion and/or deletions using single- or double-stranded DNA cutting.
