GSM2221582: H3 ChIP-seq, Epididymal white adipose tissue; Mus musculus; ChIP-Seq
Interscapular BAT and epididymal WAT were isolated and processed separately for each sacrificed mouse. The tissues were immediately minced, crosslinked in 1 % formaldehyde/PBS, and stored at -80 C. For each fat pad, material from 3-4 mice was used for sequencing. To prepare ChIP extracts, frozen crosslinked tissue was thawed and suspended ChIP buffer (50 mM HEPES/NaOH pH 7.5, 140 mM NaCl, 1 mM EDTA, 1% Triton X-100, 0.1% Na-Deoxycholate and Complete protease inhibitor) supplemented with 0.1% SDS. Samples were incubated at 4 C for 10 min, and subjected to microtip probe sonication under conditions optimized for IP efficiency. Extracts were cleared of insoluble lipid by microfuge centrifugation at full speed followed by extract transfer to a new tube. The process was repeated until minimal lipid accumulated at the top of the extract after centrifugation. ChIP-Seq libraries were produced and sequenced according to Illumina protocols. Libraries were multiplexed for sequencing.
