title: GSM1418961: H3K4me1 ChIP (DMSO); Homo sapiens; ChIP-Seq
library_construction_protocol: For ChIP-seq, cells were crosslinked with formaldehyde (1% final) for 10min at room temperature, and harvested for sonication.  Nuclei were extracted and chromatin was sheared to an average size of 200bp using a Diagenode Bioruptor. For RNA-seq, cells were harvested and PolyA+ RNA was isolated using the NEBNext Ultra RNA-seq Isolation Module. For ATAC-seq, cells were harvested, nuclei were prepped,and transposase was added for 30 minutes at 30C. Sequencing libraries for ChIP-seq were constructd using the NEBNext Ultra kit as per manufacturer's recommended instructions Sequencing libraries for ATAC-seq were constructed using custom Nextera-compatible primers, from Nextera-adapted DNA fragments
