title: GSM1216739: CHIP_DL23_nt_H3; Homo sapiens; ChIP-Seq
library_construction_protocol: Chromatin was additionally sheared, end-repaired, sequencing adaptors were ligated and the library was amplified by LMPCR. After LMPCR, the library was purified and checked for the proper size range and for the absence of adaptor dimers on a 2% agarose gel and sequenced on SOLiD sequencer to produce 50-bp long reads. 4-hydroxy-tamoxifen (4OHT) from Sigma, was dissolved in ethanol and added to cells at a final concentration of 1uM. Cells were treated with PKB inhibitor VIII (Santa Cruz) at a concentration of 10uM. Cells were grown in the absence or 4 hour presence of 4OHT or PKB inhibitor. Three independent batches of chromatin were obtained for all three conditions and mixed, with a total of 80x106 cells per IP. IPs were performed for 16h with the following antibodies: 2.5 ug of H3K4me1, H3K4me3 and H3K27ac and total H3 from Abcam (ab8895, ab8580 and ab4729, ab1791) and 16ug of αFOXO3 (Santa Cruz, H144) for the FOXO3-ER (2) ChIP-seq. The second H3K27ac(2) ChIP-seq was performed on an independent fourth batch of chromatin.
