  • Publication number: 20120149012
    Abstract: The present teachings provide DNA methylation quantification methods that avoid bisulfite treatment of DNA. Methylation-specific binding proteins (MeDNA binding proteins) and non-methylation specific binding proteins (non-MeDNA binding proteins) are employed in various embodiments to modulate the accessibility of nucleic acids to primer extension reactions. After selectively removing the target nucleic acids, the extension products can be analyzed and methylation quantitated. In some embodiments, the analysis comprises real-time PCR.

  • Publication number: 20100113285
    Abstract: A method of using a standard to correct for variability in sample handling, can comprise (a) adding a template of known concentration to an assay comprising a sample; (b) preamplifying the assay; (c) amplifying the assay; (d) collecting data during the amplifying; and (e) correcting the data using a comparison of data collected from the template to data collected from the sample.
