Source name |

|
Organism |
Homo sapiens |
Characteristics |
tissue: F cell line: OS152 cell line cell type: metastatic osteosarcoma cell line genotype: MYC amplified, CN40 treatment: m6dA methylated
|
Treatment protocol |
Isolated OS152 nuclei were methylated (10uL EcoGII per 1-2e6 nuclei) with non-specific adenine methyltransferase EcoGII (New England Biolabs, HC stock 2.5e4U/mL) at 37°C for 30 minutes, supplemented with SAM to 1.16mM (NEB) after 15 minutes. Isolated nuclei (methylated or unmethylated) were tagmented with H-Tn5-R27S,E54K,L372P (QB3 MarcoLab) at 55°C for 1hr.
|
Growth protocol |
OS152 cells were cultured in standard 1x DMEM supplemented with 10% Fetal Bovine Serum and 1% 100x Penicillin-Streptomycin-Glutamine.
|
Extracted molecule |
genomic DNA |
Extraction protocol |
Tagmented nuclei were pre-treated with 10uL RNaseA at 37°C for 15 minutes, then purified with 2.5uL Proteinase K (20mg/mL), 2.5uL 10% SDS, and 2.5uL 0.5mM EDTA at 60°C for 1-2 hours with continuous shaking at 1000 rpm. DNA was extracted with 2x SPRI bead cleanup. Tagmented fragments were gap-repaired using Phusion DNA polymerase and Taq Ligase, or T4 DNA polymerase and Ampligase, at 37ºC for 1hr, digested with Exonuclease III at 37ºC for 1hr, then cleaned up using Ampure PB. Library quality was assessed with Qubit 1x High Sensitivity DNA Assay and Agilent Bioanalyzer High Sensitivity DNA kit.
