title: GSM2221762: CHG274; Homo sapiens; ChIP-Seq
library_construction_protocol: Fresh-frozen cancer and normal tissues were dissected using a razor blade in liquid nitrogen to obtain ~5mg sized piece for each ChIP. Tissue pieces were fixed in 1% formaldehyde/PBS buffer for 10 min at room temperature. Fixation was stopped by addition of glycine to a final concentration of 125 mM. Tissue pieces were washed 3 times with TBSE buffer, and wrapped tightly with foil. Foil wrapped tissue was snap frozen in liquid nitrogen for about 10 sec. The frozen tissue was immediately pulverized. Pelleted cells and pulverized tissues were lysed in 100 µl 1% SDS lysis buffer and sonicated to 300-500bp using a Bioruptor (Diagenode). ChIPs were performed using the following antibodies: H3K4me3 (07-473, Millipore); H3K4me1 (ab8895, Abcam); H3K27ac (ab4729, Abcam) using same chromatin preparation.
