Latest Patents

One of Nobori's latest patents is a method for detecting methylated DNA. This innovative approach provides a rapid and simple way to identify methylated DNA through a series of steps. The method involves treating sample DNA with hydrogen sulfite, amplifying the treated DNA using PCR, and then subjecting the resultant PCR amplification product to ion-exchange chromatography. Another notable patent involves nucleic acids encoding methyladenosine phosphatase (MTAse). This method detects the presence of MTAse in a cell sample by adding oligonucleotide probes that specifically hybridize to any MTAse encoding nucleic acid in the sample. The absence of MTAse is considered indicative of malignancy, highlighting the potential clinical applications of his work.
