Pyrosequencing is a technique that uses a sequencing-by-synthesis system which is
designed to quantify single-nucleotide polymorphisms (SNPs). Artificial C/T SNP
creation via bisulfite modification permits measurement of DNA methylation
locally and globally in real time. Alteration in DNA methylation has been
implicated in aging, as well as aging-related conditions such as cancer, as well
as cardiovascular, neurodegenerative, and autoimmune diseases. Considering its
ubiquitous presence in divergent clinical pathologies, quantitative analysis of
DNA CpG methylation both globally and at individual genes helps to elucidate the
regulation of genes involved in pathophysiological conditions. The ability to
detect and quantify the methylation pattern of DNA has the potential to serve as
an early detection marker and potential drug target for several diseases. Here,
we provide a detailed technical protocol for pyrosequencing supplemented by
critical information about assay design and nuances of the system that provides a
strong foundation for beginners in the field.
