The experimental strategy adopted to map this profile involved isolation of replication products from HeLa cells synchronized at the G1-S boundary by thymidine-aphidicolin double block. Cells released from the block were labeled with BrdU at every two-hour interval of the 10 hours of S-phase and DNA was isolated from them. The heavy-light(H/L) DNA representing the pool of DNA replicated during each two-hour labeling period was separated from the unlabeled DNA by double cesium chloride density gradient centrifugation. The purified heavy-light DNA was then hybridized to a high-density genome-tiling Affymetrix array comprised of all unique probes within the ENCODE regions.
