GSM8012192: pif4-22°C, H4K5ac, ChIP; Arabidopsis thaliana; ChIP-Seq
Seedlings were harvested and fixed with the buffer containing 0.4 M sucrose, 10 mM Tris-HCl (pH 8.0), 1 mM EDTA, 1% formaldehyde, and 1 mM PMSF.Chromatin was sonicated into DNA fragments around 200~500-bp in size using lysis buffer containing 50 mM HEPES (pH 7.5), 150 mM NaCl, 1 mM EDTA, 1 mM PMSF, 1% SDS, 0.1% Na deoxycholate, 1% Triton X-100 and Protease Inhibitor cocktail. The ChIP-seq libraries were constructed by following the manufacturer's instructions of VAHTSTM Universal DNA Library Prep Kit (Vazyme).
