Publication number: 20120149012Abstract: 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.Type: ApplicationFiled: July 11, 2011Publication date: June 14, 2012Applicant: LIFE TECHNOLOGIES CORPORATIONInventors: Shoulian Dong, Junko F. Stevens
