  • Patent number: 11319533
    Abstract: The present invention relates to a CRISPR nanocomplex for nonviral genome editing, a method for preparing the same, and the like. The CRISPR nanocomplex for nonviral genome editing of the present invention has a size of several nanometers to several microns, enables intracellular delivery without external physical stimulation, and can be utilized for genome editing through nonviral routes with respect to target genes of cells. As a result, when used for preparation of animal model, microbiological engineering, cell engineering for disease treatment, or formulations for biological administration, the CRISPR Nanocomplex shows high intracellular delivery and gene editing efficiency, and can minimize problems, such as nonspecific editing, gene mutation, and induction of cytotoxicity and biotoxicity.
    Type: Grant

  • Patent number: 10274490
    Abstract: The present invention provides novel methods of magnetically labeling a bacterial cell by contacting the call with an affinity ligand and subsequently contacting the cell with a magnetic agent, where the affinity ligand and magnetic agent include bioorthogonally reactive groups that can react with each other to form a covalent bond. Compounds, compositions, kits and applications of the method are also described.
