title: GSM7679360: ChIP_PHOX2B_IMR32_DMSO_rep2; Homo sapiens; ChIP-Seq
library_construction_protocol: Lysates were obtained from sonicated nuclei crosslinked with either 1% formaldehyde and 2 mM disuccinimidyl glutarate (double cross-linking) for ASCL1, or 1% formaldehyde alone (single cross-linking) for all other targets. Protein-DNA complexes were isolated by immunoprecipitation. All libraries were barcoded and prepared for sequencing using standard Illumina protocols.
