http://tcyfl.net/parents.php WebDec 23, 2008 · The mechanism underlying enhancer-blocking by insulators is unclear. We explored the activity of human β-globin HS5, the orthologue of the CTCF-dependent chicken HS4 insulator. An extra copy of HS5 placed between the β-globin locus control region (LCR) and downstream genes on a transgene fulfills the classic predictions for an enhancer …

WebDec 7, 2024 · Either CTCF or YY1 antibodies were used to enrich protein-bound chromatin fragments exactly as described in the ChIP-seq section. A portion of ChIP DNA was eluted from antibody-coated beads for concentration quantification and for enrichment analysis using qPCR. For ChIA-PET library construction ChIP DNA fragments were end-repaired … WebCTCF is an architectural protein with a critical role in connecting higher-order chromatin folding in pluripotent stem cells. To elucidate the role for CTCF in the establishment of 3D chromatin configurations specific to the neural lineage, we analyze CTCF occupancy and fine-scale chromatin folding across cellular models of early development.
