Description
osteosarcoma from the tibia of a 15 year old, J. Ponten and E. Saksela derived this line (originally 2T) in 1964 from a moderately differentiated sarcoma, viruses were not detected during co-cultivation with WI-38 cells or in CF tests against SV40, RSV or adenoviruses, mycoplasma contamination was detected and eliminated in 1972, (PMID: 6081590)

library_construction_protocol
Cells were crosslinked with 1% formaldehyde at room temperature for 1 hour, quenched with 0.125M Glycine and washed with PBS. Chromatin was isolated using a lysis buffer containing 1% SDS, 50 mM Tris-HCl (pH 8.0), and 10 mM EDTA. The chromatin extracts were sonicated for 20 min (in repeated cycles of 30-s on/30-s off) using a Bioruptor (Diagenode) kept at 4 °C with a circulating water bath to achieve a DNA fragment size of 300–400 bp.
