  • Patent number: 11952570
    Abstract: Methods are provided for the isolation and analysis of circular DNA from complex samples, based on the topology of the DNA molecule. A sample comprising DNA species is combined with a chaotropic dense salt solution. A fraction containing the circular DNA of interest is isolated and dialyzed to remove excess salt. In some embodiments salt gradients are generated by ultracentrifugation in the absence of intercalating dyes, e.g. ethidium bromide; and in the absence of protease digestion. The circular DNA thus isolated is substantially pure, e.g. greater than about 75%, greater than about 80%, greater than about 90%, greater than about 95% of DNA in the isolated fraction is comprised of circular DNA.

  • 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: 11891609
    Abstract: The present disclosure relates to methods for increasing observed editing rates in the surviving bacteria cells. The compositions and methods presented herein in combination lead to a phenomenon of “edit or die.” Although less cells survive plating and editing, a large percentage of cells that do survive are multiple editors. In one experiment it was found that if a cell survives transformation, plating, and editing, 75% of the surviving cells are multiple editors; that is, 75% of the surviving cells were simultaneously edited with edits at two or more different locations within the bacterial genome.

  • Patent number: 11866715
    Abstract: Disclosed herein are novel Pichia pastoris strains for expression of exogenous proteins with substantially homogeneous N-glycans. The strains are genetically engineered to include a mutant OCH1 allele which is transcribed into an mRNA coding for a mutant OCH1 gene product (i.e., ?-1,6-mannosyltransferase, or “OCH1 protein”). The mutant OCH1 protein contains a catalytic domain substantially identical to that of the wild type OCH1 protein, but lacks an N-terminal sequence necessary to target the OCH1 protein to the Golgi apparatus. The strains disclosed herein are robust, stable, and transformable, and the mutant OCH1 allele and the ability to produce substantially homogeneous N-glycans are maintained for generations after rounds of freezing and thawing and after subsequent transformations.
