This method allows precise analysis of methylation in a certain region by converting all nonmethylated cytosines into tymines, while methylated cytosines remain unchanged. Dr. A. Gratchev Methods.info - [Read Analysis of methylation using bisulphite sequencing]
Adapted from Frommer et.al. Good protocol for bisulfite treatment of DNA. Includes tips on Methylation PCR for CpG methylation analysis. University of Texas M. D. Anderson Cancer Center - [Read Bisulfite Treatment of DNA for Methylation Analysis]
A detailed protocol for bisulfite treatment of DNA. DNA is first digested with a restriction enzyme. DNA is denauted at 97C for 5min. Bisulfite protocol is included. Also DNA purification using the Promega Wizard DNA Cleanup kit in indicated. Fan Lab. UCL - [Read Fan Lab Bisulfite Treatment of Genomic DNA]
Hairpin-bisulfite PCR will be a powerful tool in studying other processes for which genetic or epigenetic information differs on the two complementary strands of DNA. Laird et al., 2003. PNAS - [Read Hairpin-bisulfite PCR: Assessing epigenetic]
Single Nucleotide Primer Extension can be used for the analysis of methylation in a certain position. Treat DNA with bisulphite and then anneal a primer which ends immediately before the site of analysis. Dr. A. Gratchev Methods.info - [Read Singel Nucleotide Primer Extension (SNuPE)]
