The pattern and extent of DNA methylation can significantly affect the success of restriction digestions
or bacterial transformations. Prokaryotic DNA may be methylated by host restriction/modification
systems, while eukaryotic DNA often is methylated i - [Read A practical guide to DNA methylation Promega PDF]
Protocol for the analysis of DNA methylation using bisulphite sequencing. Method allows precise analysis of methylation in a certain region by converting all nonmethylated cytosines into tymines, while methylated cytosines remain unchanged. This method requires small amount of genomic DNA and therefore seems to be very useful for the analysis of clinical samples, where the material amount is limited. - [Read Analysis of DNA Methylation using Bisulphite Sequencing Protocol]

Investigators can utilize X chromosome inactivation (methylation) to determine the clonality status of a tumor or premalignant lesion in females. The technique is based on a methylation-sensitive restriction enzyme and analysis of a polymorphic locus on the X chromosome. Clonal cell populations will show "loss" of the non-methylated allele after restriction digest. The assay can be performed on DNA recovered from microdissected samples. Both frozen tissue and fixed-embedded tissue can be used. - [Read Clonality - X Chromosome Inactivation Assay Protocol]
