Kunihara Ijiro has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Nucleic acid polymer/intercalator monolayer and methods of using and making thereof
    Patent number: 6020131
    Abstract: The present invention has an object to provide an easy method for detecting a nucleic acid polymer in aqueous phase.The present invention provides a method for detecting the amount of nucleic acid polymer, which comprises the steps of modifying an intercalator to be amphiphilic by using a hydrophobic group, spreading the amphiphilic intercalator on an aqueous solution containing a nucleic acid polymer to form a monolayer of said nucleic acid polymer and said amphiphilic intercalator at the gas-water interface, and measuring surface pressures per unit area of said monolayer.
    Type: Grant
    Filed: November 7, 1997
    Date of Patent: February 1, 2000
    Assignee: Research Development Corporation of Japan
    Inventors: Kunihara Ijiro, Masatsugu Shimomura
