comment:Chromosome conformation capture technologies are used to study the structural properties and spatial organization of chromosomes inside cells. All types of chromosome conformation capture technology involve five primary steps: cross-linking of DNA in vivo, restriction digestion, intramolecular ligation, reversing cross-linkages, and DNA enrichment and quantitation. The last step is different for each type of chromosome conformation capture technology, and may include PCR (3C), inverse PCR (4C), or ligation-mediated amplification (5C). Methods for product quantitation can include agarose gel detection or real-time quantitative PCR in the case of 3C, or high-throughput sequencing or microarray analysis for 4C and 5C.
