Abstract
Chromosome conformation capture (3C) is a method for studying chromosomal organization that takes advantage of formaldehyde cross-linking to measure the spatial association of two pieces of chromatin. The 3C method begins with whole-cell formaldehyde fixation of chromatin. After cell lysis, solubilized chromatin is digested with a type II restriction endonuclease, and cross-linked DNA fragments are ligated together. Cross-links are reversed by degradation with proteinase K, and chimeric DNA molecules are purified by standard phenol:chloroform extraction. The resulting 3C library represents chromatin fragments that may be separated by large genomic distances or located on different chromosomes, but are close enough in three-dimensional space for cross-linking. Locus-specific oligonucleotide primers are used to detect interactions of interest in the 3C library using end-point polymerase chain reaction (PCR).
