  • Nucleic acid nanotube liquid crystals
    Patent number: 9371552
    Abstract: Compositions and methods for preparing nucleic acid nanotubes using DNA origami techniques are described, which provide for nanotubes of predictable and uniform length. The nucleic acid nanotubes thus formed are suitable as liquid crystal preparations enabling liquid-crystal NMR spectroscopy of proteins solubilized in detergent.
    Type: Grant
    Filed: April 20, 2011
    Date of Patent: June 21, 2016
    Assignees: Dana-Farber Cancer Institute, Inc., President and Fellows of Harvard College
    Inventors: William M. Shih, Shawn M. Douglas, James J. Chou
