		In vertebrates, DNA methylation typically occurs at CpG sites, where a cytosine is directly followed by a guanine in the DNA sequence.
		CpG sites are often found at higher density near gene promoters where they are collectively referred to as CpG islands.
		Two base-specific cleavage reactions (T reverse and C reverse) are performed to discover methylation sites and to determine methylation ratios within a given target region.

	CpG site - Wikipedia, the free encyclopedia
		CpG sites are regions of the DNA where a cytosine nucleotide occurs next to a guanine nucleotide.
		CpG sites thus tend to be eliminated from the genomes of eukaryotes.
		Surprisingly, these CpG sites are unmethylated, and therefore any spontaneous deaminations of cytosine to uracil are recognized by the repair machinery and the CpG site is restored.

	CpG site (Site not responding. Last check: 2007-10-19)
		CpG sites are regions of the DNA where a cytosine nucleotide is situated next to a guanine nucleotide.
		Despite the high probability of a cytosine and guanine lying next to each other in a random nucleotide sequence, there are actually very few CpG sites in the eukaryotic genomes.
		If this mutation has no effect (as in most cases), the error is not recognized by the repair machinery, thus resulting in the loss of the CpG site.

	Rules of primer design for methylation experiments
		If CpG island prediction is not used for primer selection (default), PCR products must span a minimal number of CpG sites specified by user (default: 5).
		Primers should contain at least one CpG site within their sequence, and the CpG site should preferably be located in the most 3’-end of their sequence to discriminate methylated DNA against unmethylated DNA.
		If CpG island prediction is used for primer design and more than one island is found, any of the predicted island will be the target region for amplification.

	A partial methylation profile for a CpG site is stably maintained in mammalian tissues and cultured cell lines. (Site not responding. Last check: 2007-10-19)
		This site was found to be methylated at a level of approximately 25% in mouse brain, kidney, lung, and skeletal muscle tissues, at a level close to 50% in liver, and at level close to 0% in testis.
		A methylation profile of approximately 25% at this CpG site was also observed in five mouse teratocarcinoma stem cell lines and one additional cultured cell line.
		We conclude that partial methylation of a specific CpG site can be stably maintained both in vivo and in vitro and that a mechanism exists for its maintenance.

	Rapid quantitation of methylation differences at specific sites using methylation-sensitive single nucleotide primer ... (Site not responding. Last check: 2007-10-19)
		Changes in methylation patterns at specific CpG sites are routinely monitored by digestion of genomic DNA with methylation-sensitive restriction enzymes followed by Southern analysis of the region(s) of interest.
		The intensities of bands in the C lanes were proportional to the percent methylation at each CpG site being monitored and band intensities in the T lanes were proportional to the percent of unmethylated cytosine.
		Furthermore, the amount of methylation at multiple CpG sites can be analyzed in a single reaction by using a multiplex oligonucleotide strategy and without the use of restriction enzymes.
