Chromosome conformation capture carbon copy (5C) is a high-throughput method for detecting ligation products of interest in a chromosome conformation capture (3C) library. 5C uses ligation-mediated amplification (LMA) to generate carbon copies of 3C ligation product junctions using single-stranded oligonucleotide probes. This procedure produces a 5C library of short DNA molecules which represent the interactions between the corresponding restriction fragments. The 5C library can be amplified using universal primers containing the Illumina paired-end adaptor sequences for subsequent high-throughput sequencing.
