| Hybridization protocol |
Oligoarray control targets and hybridization buffer (Agilent In Situ Hybridization Kit Plus) were added, and samples were applied to microarrays enclosed in Agilent SureHyb-enabled hybridization chambers. After hybridization, slides were washed sequentially with 6x SSC/0.005% Triton X-102 and 0.1x SSC/0.005% Triton X-102 before scanning. Slides were hybridized for 17 h at 60°C in a rotating oven, and washed.

| Scan protocol |
Scanned on an Agilent G2565AA scanner.

| Description |
Biological replicate 2 of 4. Control embryonic stem cells, untreated, harvested after several passages.
