  • Patent number: 11708566
    Abstract: Recombinant DP04-type DNA polymerase variants with amino acid substitutions that confer modified properties upon the polymerase for improved single molecule sequencing applications are provided. Such properties may include enhanced binding and incorporation of bulky nucleotide analog substrates into daughter strands and the like. Also provided are compositions comprising such DP04 variants and nucleotide analogs, as well as nucleic acids which encode the polymerases with the aforementioned phenotypes.
    Type: Grant

  • Publication number: 20140235790
    Abstract: Provided herein are compositions and methods for intracellular delivery. The compositions are polymer compositions in which the polymer serves as a carrier for therapeutic and/or diagnostic agents. The polymer compositions are effective in targeted delivery of therapeutic and/or diagnostic agents to a cell. The polymer compositions include a targeting moiety that includes carbohydrate groups that effectively target specific cell surface receptors. The polymer compositions also include an agent binding moiety that effectively associates the therapeutic and/or diagnostic agent to be delivered to the cell.
