title: GSM4018836: HCT116_ChIPseq_HP1beta_rep1; Homo sapiens; ChIP-Seq
library_construction_protocol: Cells were grown to ~75% confluency, harvested with trypsin, washed in 1X PBS, and frozen/stored at -80°C. Thawed cells were fixed in 1% formaldehyde and quenched in 0.125M Glycine, then washed twice in 1X PBS. Fixed cells were then resuspended in 500ul lysis buffer (50mM Tris-HCl pH 8.0, 10mM NaCl, 0.2% NP40, 1X PITC) for 30 min on ice with periodic resuspension. Libraries were prepared using NEB UltraII DNA library kit
