Specificity of Methylation Assays in Cancer Research : A Guideline for Designing Primers and Probes

Abstract EN

DNA methylation is an epigenetic regulation mechanism of genomic function, and aberrant methylation pattern has been found to be a common event in many diseases and human cancers.

A large number of cancer studies have been focused on identification of methylation changes as biomarkers (i.e., breast cancer).

However, still clinical use of them is very limited because of lack of specificity and sensitivity for diagnostic test.

This highlights the critical need for specific primer and probe design to avoid false-positive detection of methylation profiling.

The guideline and online web tools that are introduced in this paper might help to perform a successful experiment and to develop specific diagnosis biomarkers by designing right primer pair and probe prior to experimental step.
