Patents by Inventor Nikolai Lisitsyn

Nikolai Lisitsyn 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).

  • Publication number: 20040197774
    Abstract: Methodology is provided for developing probes for identifying sequence differences between two related DNA populations, sets of DNA fragments or collections of restriction-endonuclease-cleaved DNA or cDNA. The method employs an initial stage to obtain a representation of both DNA populations, namely using the PCR to produce relatively short fragments, referred to as amplicons. Tester amplicons containing target DNA, sequences of interest, are ligated to adaptors and mixed with excess driver amplicons under melting and annealing conditions, followed by PCR amplification. The process may be repeated so as to greatly enrich the target DNA. Optionally, the target DNA may then be cloned and the DNA used as probes.

  • Patent number: 6350576
    Abstract: Nucleic acid sequence probes are provided for the detection of lesions associated with neoplastic cells. The sequences can be used for identifying the locus associated with the lesion, for determining cancer susceptibility of cells, as well as categorizing and characterizing tumor cells for prognosis and therapy.
