Koji Nagafuji 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).

  • Method for producing circular DNA formed from single-molecule DNA
    Patent number: 9434941
    Abstract: There is provided a method for producing a circular DNA which consists of a circular DNA formed from a single-molecule DNA and which does not comprise circular DNA formed from multiple-molecule DNA. According to the method of the present invention, a circular DNA molecule formed only from a single-molecule DNA can be reliably produced.
    Type: Grant
    Filed: January 12, 2015
    Date of Patent: September 6, 2016
    Assignee: KURUME UNIVERSITY
    Inventors: Shinichi Mizuno, Koji Nagafuji, Takashi Okamura
  • Method for exclusive selection of circularized DNA from monomolecular DNA in circularizing DNA molecules
    Patent number: 9416358
    Abstract: The present invention provides a method for producing a circular DNA molecule having a specific structure that enables to distinguish circular DNA formed from a single DNA molecule (single-molecule circular DNA), from circular DNA formed from multiple DNA molecules (multiple-molecule circular DNA) and also from single-molecule circular DNA derived from the circular DNA formed from multiple DNA molecules. According to the present invention, only single-molecule circular DNA that is not derived from multiple-molecule circular DNA can be selected in the production of circular DNA.
    Type: Grant
