title: GSM3904588: DamID, Dam-LMNB1, F121-9, Morc1 ABCdel, cloneA12, rep4; Mus musculus; OTHER
library_construction_protocol: DamID-seq was performed as described in (Brueckner et al. 2016) with slight modifications. Instead of plasmid transfections, Dam-LMNB1 or Dam were added by Lentiviral transduction. Three days after infection, cells were collected for gDNA isolation. gDNA was pre-treated with SAP (10 U, New England Biolabs) in CutSmart buffer in a total volume of 10 µl at 37 °C for 1 h followed by heat inactivation at 65°C for 20 min to remove signal from apoptotic fragments. gDNA was digested with DpnI (10 U, New England Biolabs) in CutSmart buffer in a total volume of 10 µl at 37 °C for 8 h followed by heat inactivation at 80 °C for 20 min. Fragments were ligated to 12.5 pmol DamID adapters using T4 ligase (2.5 U, New England Biolabs) in T4 ligase buffer in a total volume of 20 µl incubated at 16 °C for 16 h. The reaction was heat inactivated for 10 min at 65 °C. Products were then digested with DpnII to remove partially methylated fragments. DpnII buffer and DpnII (10 U, New England Biolabs) were added in a total volume of 50 µl and incubated at 37 °C for 1 h. 8 µl of DpnII-digested products was amplified by PCR with MyTaq Red Mix (Bioline) and 2.5 µM primers Adr-PCR-Rand1 in a total volume of 40 µl. PCR settings were 8 min at 72 °C (1×) followed by 20 s at 94 °C, 30 s at 58 °C, 20 s at 72 °C (24× for Dam, 28x for DamLMNB1 samples) and 2 min at 72 °C (1×). Remaining steps were performed as previously described. DamID-seq was performed as described in (Brueckner et al. 2016) with slight modifications.
