One of the most significant challenges in PCR design of bisulfite-converted genomic DNA is the design and optimization of primers to reduce PCR bias. When aiming to preserve the quantitative ratio of methylated-to-unmethylated CpG sites for quantitative methylation, it is imperative that the primer design be un-biased so that it will not select for one type of fragment over another.

Product Details
The nature of methylation analysis is that methylated and unmethylated DNA molecules will be amplified with greatly differing efficiencies. This is due to secondary structure formation (primer loops and dimers, template loops, mispriming) and long strings of T’s and G’s and C/T variation at CpG sites. Primers situated on CpG sites can selectively amplify either the methylated or unmethylated fragment, possibly producing bias in the final methylation analysis.
