Methylation Sensitive Single Nucleotide Primer Extension Ms-SNuPE

Posted on

This method allows you to analyze several CpG dinucleotides in a single reaction. Paired primer extensions with 32P linked dCTP or TTP will reveal whether a Cytosine is methylated or not. Primers are made that anneal to the PCR template and terminate subsequently 5 prime of the cytosine to be assayed. This will quantitatively assess the ratio of methylated and unmethylated cytosines in the DNA sample at that specific CpG dinucleotide.
