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
DNA from asynchronous cell cultures was isolated, size fractionated and subject to exunuclease digestion as described in Aladjem et al., Science 281, 1005, 1998. and Wang et al., Molecular and Cellular Biology 24:3373-86, 2004. For ChipSeq, DNA molecules were enriched using each antibodies. Enriched DNA molecules were then amplified randam primer with klenow fragment and sequenced by Illumina Genome Analyzer IIx. Illumina Genomic DNA protocol (Illumina Paired-END DNA Sample Prep Kit). Illumina paired-end sequencing
