Sample type |
SRA |

|
Source name |
k562 Cell lines
|
Organism |
Homo sapiens |
Characteristics |
cell line: k562 digestion: MspI treatment: bisulfite
|
Treatment protocol |
Genomic DNA was isolated from the cell lines. DNA was digested with MspI (NEB), a methylation-insensitive enzyme that cuts C’CGG. Digested DNA was size selected on a 4% NuSieve 3:1 Agarose gel (Lonza). For each sample, two slices containing DNA fragments of 40-120 bp and 120-220 bp, respectively, were excised from the unstained preparative portion of the gel. These two size fractions were kept apart throughout the procedure including the final sequencing. Pre-annealed Illumina adaptors containing 5’-methyl-cytosine instead of cytosine were ligated to size-selected MspI fragments. Adapter-ligated fragments were bisulfite-treated using the EZ DNA Methylation kit (Zymo Research, Orange, CA). The products were PCR amplified, size selected, and sequenced on the Illumina GA IIxat a reading length of 36 bp.

Growth protocol |
hES, LiPS 1 and LiPS3 cells were grown in ES KO DMEM supplemented with 15% KSR serumn in presence of 5ng/ml FGF, at 37 °C in a humidified atmosphere with 5% CO2 K562 cells were grown in DMEM supplemented with 10% FBS , at 37 °C in a humidified atmosphere with 5% CO2
