e/Restriction landmark genomic scanning

Information
has gloss	eng: Restriction Landmark Genomic Scanning (or RLGS) is a genome analysis method that allows for rapid simultaneous visualization of thousands of landmarks, or restriction sites. Using a combination of restriction enzymes some of which are specific to DNA modifications, the technique can be used to visualize differences in methylation levels across the genome of a given organism. RLGS employs direct labeling of DNA, which is first cut by a specific series of restriction enzymes, and then labeled by a radioactive isotope (usually phosphorus-32). A two-dimensional electrophoresis process is then employed, yielding high-resolution results. The radioactive second-dimension gel is then allowed to expose a large sheet of film. The radiation produced by the radioactive labeling will cause the film to be exposed wherever the restriction fragments have migrated during electrophoresis.
