GSM6997599: MDA-MB-231 DSM OE; Homo sapiens; ChIP-Seq
The cells were resuspended in a swelling buffer in the presence of the protease inhibitor cocktail (Sigma) and then pelleted and resuspended in the SDS lysis buffer. The lysates were transferred to a Covaris microTUBE and sonicated with an E220 Covaris Ultrasonicator. Chromatin fragmentation (~500 bps) was verified through agarose gel electrophoresis. DNA was extracted using Qiagen mini prep based on manufacturer instructions. DNA libraries were prepared for sequencing using standard ChIP Illumina protocols
