  • Publication number: 20200299729
    Abstract: The present disclosure relates to methods, kits, and compositions for improving the efficiency of homologous recombination. In particular, the disclosure relates to methods for introducing a nucleic acid cutting entity for DNA editing into cells that are difficult to transfect. Generally, the nucleic acid cutting entity is introduced into the cell without the use of viral vectors. The disclosure also relates to cloning DNA molecules directly into a genome with the combined use of promoter trapping and short homology arms, nuclear localization signal, and/or binding one or more DNA binding agents (TAL effector domain or truncated guide RNA bound by Cas9) to specific sites thereby displacing or restructuring chromatin at the target locus, and/or it increasing the accessibility of the target locus to further enzymatic modifications. The methods and compositions provided herein are, inter alia, useful for genome editing and enhancing enzymatic processes involved therein.

  • Patent number: 10753905
    Abstract: The invention provides methods for quantifying biomolecules, such as polypeptides in mass spectrometric analysis. The methods include use of a biomolecule standard having at least one atomic isotope different than that of the naturally occurring isotopes in the biomolecule of interest. Methods of the present invention also include methods for quantifying biomolecules where the copy biomolecule standard is made by expressing the biomolecule using a recombinant cell. Further included are the biomolecule standards themselves, method for making such standards, kits, systems, reagents, and engineered cells relating to the use of biomolecule standards in mass spectrometric analysis.
