Circularized chromosome conformation capture
All 3C methods start with a similar set of steps, performed on a sample of cells. First, the cell genomes are cross-linked with formaldehyde, which introduces bonds that "freeze" interactions between genomic loci. Treatment of cells with 1-3% formaldehyde, for 10-30min at room temperature is most common, however, standardization for preventing high protein-DNA cross linking is necessary, a… WebTethered Conformation Capture is a modified Hi-C approach in which key reactions like marking of the DNA ends and circularization.....are performed on a soli...

WebApr 20, 2024 · Chromosome conformation capture is a research method that allows researchers to observe interactions between genetic loci that are in close contact in the 3-dimensional structure of a chromosome but can be megabases apart in … WebA modification of 3C, circularized chromosome conformation capture (4C), has the advantage that the sequence of only one site of interest needs to be known. The sequences of all loci that interact with the chosen locus can be determined by inverse PCR, followed by hybridization to microarrays or high-throughput sequencing [4, 5].
