  • Publication number: 20120003663
    Abstract: This invention is related to a method for rapidly quantifying hydroxymethylated DNA by binding DNA to a plastic carrier followed by immunodetection of 5-hydroxymethylcytosine or a hydroxymethylcytosine structure that is marker of DNA hydroxymethylation.
    Type: Application
    Filed: July 1, 2010
    Publication date: January 5, 2012
    Inventors: Weiwei Li, Jessica Li
  • Patent number: 7785793
    Abstract: This invention is related to a method and assay kit for rapidly quantifying global DNA methylation through immobilizing DNA by simple dry-capture on the plastic carrier followed by immunodetection of 5-methylcytosine structure that is the marker of DNA methylation.
    Type: Grant
    Filed: October 9, 2008
    Date of Patent: August 31, 2010
    Inventors: Weiwei Li, Jessica Li
  • Publication number: 20100068720
    Abstract: This invention is related to a method for the detection of early or pre-cancer using DNA isolated from blood and body fluids. This invention provides an improved methylation-based PCR assay, a panel of methylated-based cancer-related gene markers for the detection of general cancer and a panel of unmethylation-based tissue- or cell-specific gene markers for discriminating different type of cancer detected from blood samples. This method couples a sequential cancer-related gene marker detection and tissue or cell-specific gene marker assay and is particularly useful as a simultaneous screening test for following type of cancer: lung, breast, ovarian, colon, stomach, prostatic, pancreatic and liver cancer.

  • Publication number: 20090326209
    Abstract: This invention is related a method for rapidly isolating and modifying DNA from plasma/serum and body fluids. This invention provides a procedure and composition to obtain a high yield of modified DNA for methylation-specific PCR assay by coupling DNA isolation and modification courses.

This invention provides an improved methylation-based PCR assay, a panel of methylated-based cancer-related gene markers for the detection of general cancer and a panel of demethylation-based tissue- or cell-specific gene markers for discriminating different type of cancer detected from blood samples. This method couples a sequential cancer-related gene marker detection and tissue or cell-specific gene marker assay and is particularly useful as a simultaneous screening test for following type of cancer: lung, breast, ovarian, colon, stomach, prostatic, pancreatic and liver cancer.
