Y adding 125 mmol/L glycine. Cells were then washed with cold PBS, harvested and resuspended in SDS lysis buffer containing a protease inhibitor cocktail. Chromatin was sheared by sonication (typical length 0.25-1 Kb) and incubated with 60 ml protein A/G agarose/salmon sperm DNA (50 slurry; Millipore) with gentle agitation for 30 minutes. The supernatant was then immunoprecipitated with anti-SOX4 antibody 1:500 or its matched nonimmune crude serum 1:500 (IgG; Diagenode) at 4 overnight. Protein A/G agarose (60 mL of 50 slurry) was then added and incubated for 1 hour. Pellets had been washed and protein-DNA cross-links had been reversed by overnight incubation at 65 with proteinase K. DNA was purified following a traditional phenol hloroform protocol and eluted in 50 mL water. No less than 3 independent Chromatin immunoprecipitation (ChIP) experiments had been carried out.Xenografted tumor model in vivoAdditional file 1: Figure S1.
