  • Patent number: 11920128
    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.

  • Patent number: 11707056
    Abstract: The present invention is directed to the concept of sectoring antibody gene segment repertoires in order to enable the development of novel, synthetic antibody chain repertoires not seen in nature. The present invention is also directed to the realisation of the inventors that sectoring can also alter gene segment expression by providing new arrangements of gene segment clusters relative to other gene segments and regulatory elements in transgenic immunoglobulin loci, thereby providing for new synthetic antibody chain sequence repertoires. The invention also relates to gene segment inversion.
