  ChIC/CUT&RUN sequencing - Anti-CTCF antibody [EPR18253] - ChIP Grade (ab188408)

  CUT&RUN was performed using the ChIC/CUT&RUN pAG-MNAse ChIC/CUT&RUN pAG-MNase ab285373, 105 HeLa cells and 5μg of ab188408 [EPR18253]. The resulting DNA was sequenced on the Illumina NovaSeq 6000 to a depth of 10 million reads. The ChIP data was conducted on chromatin prepared from HeLa cells. Cells were fixed with 1% formaldehyde for 10 minutes. ChIP was performed with 107 HeLa cells and 4 μg of ab188408 [EPR18253]. ChIP DNA was sequenced on the Illumina NovaSeq 6000 to a depth of 30 million reads.
