Drosophila Kc cells were grown in BPYE medium (Shields and Sang M3 Insect medium, Sigma, supplemented with 25% w/v bactopeptone, 20% w/v yeast extract, 5% heat inactivated fetal calf serum, all Gibco) at 23�C. Full length Sce was cloned into pNDamMyc (van Steensel, B. & Henikoff, S. Identification of in vivo DNA targets of chromatin proteins using tethered dam methyltransferase. Nat Biotechnol 18, 424-8, 2000) and plasmid was transfected into Kc cells as described (Henikoff, S., Ahmad, K., Platero, J.S. & van Steensel, B. Heterochromatic deposition of centromeric histone H3-like proteins. Proc Natl Acad Sci U S A 97, 716-21, 2000).

Description
Embryonic Drosophila cells, Kc167 cells
Data processing
After removal of low quality, redundant or ambiguous proves, hybridization data of 9,994 probes was used for analyses, all measured ratios were log base 2-transformed and normalized to the median value of the entire array
