  • Patent number: 8257950
    Abstract: The present invention provides an improved method for the bisulfite conversion of DNA, and facilitates the analysis of cytosine methylation of genomic DNA. Novel combinations of denaturing solvents, new reaction conditions and new purification methods provide surprisingly efficacious methods for bisulfite conversion of DNA relative to prior art methods. The converted DNA may subsequently be analyzed by many different methods.
    Type: Grant
    Filed: June 13, 2011
    Date of Patent: September 4, 2012
    Assignee: Epigenomics AG
    Inventors: Kurt Berlin, Matthias Ballhause, Karen Cardon

  • Publication number: 20070184438
    Abstract: Various aspects of the present invention provide novel diagnostic and prognostic methods for detecting, or for detecting and differentiating between or among colorectal cell proliferative disorders. Preferably, said colorectal cell proliferative disorders are selected from the group consisting of colorectal carcinoma, colon adenomas, and colon polyps. The inventive methods are based on analysis of differential CpG dinucleotide methylation of genomic DNA between or among normal and disease states. Additional embodiments provide nucleic acids and oligomers (including oligonucleotides and peptide nucleic acid (PNA)-oligomers), nucleic acid arrays and kits useful for practicing said methods, and in otherwise detecting, or detecting and differentiating between or among colorectal cell proliferative disorders.
