GSM8992199: KBM7 ChIC H3K9me3 (KIN8790.index10); Homo sapiens; OTHER
double thymidine block: cells received 2 mM thymidine for 15 hours, followed by 9 hours of release, followed by a second thymidine block for 13 hours. MN was activated thorugh 2mM CaCl2 for 30min at 4C at inactivated by EGTA addition. Cells were lysed (protK + NP40), fragments end-repaired (Klenow) and adenine methylated sites were cut (DpnI). Dam and ChIC fragemnts are ligated to blunt end adaptors containing a cell barcode and unique molecular identifier and a T7 promoter. After pooling DNA is amplified by in vitro transcription, before rundom hexamer based reverse transcription and final indexing PCR for sequencing.
