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_selection: ChIP
library_construction_protocol: Cells were treated with 1% formaldehyde for 5 min at 37°C. After cell lysis, nuclei were re-suspended in RIPA buffer (10 mM Tris/HCl pH 7.5, 150 mM NaCl, 1% NP40, 1% deoxycholic acid (DOC), 0.1% SDS, 1 mM EDTA) and DNA was fragmented to a size <300 bp using Covaris. Chromatin was immunoprecipitated with 15 µg of corresponding antibody for 6 hours. Chromatin was eluted with 1% SDS and crosslinking was reverted overnight. For purification, chloroform/phenol extraction was used. Libraries were prepared according to instructions accompanying the NEBNext Ultra™ II DNA Library Prep Kit for Illumina. Purified DNA was end-repaired, A-tailed, ligated to Illumina adaptors, size-selected (200 bp) and eluted. DNA fragments were amplified by 12 to 17 cycles of PCR and library size was tested with the Fragment Analyzer (Advanced Analytical). The amount of library DNA was quantified using a picogreen assay
