GSM4721160: wild type (ndt80Δ) chip for pH2A rep 1; Saccharomyces cerevisiae; ChIP-Seq
For ChIP-seq samples, 25 ml of the meiotic cells were collected at different time points and fixed for 30 min in 1% formaldehyde. For MNase-seq samples, 50 ml of the meiotic cells were collected at the 3-hr time point and fixed for 30 min in 1% formaldehyde.  The formaldehyde was quenched with 125 mM glycine. ChIP-seq samples were processed as described in (Blitzblau et al., 2012). MNase-seq samples were processed as described in (Pan et al., 2011). A second sonication step was added just before library prep where indicated using a Bioruptor Pico (Diagenode, NJ, USA) with the following settings: 30 secs ON and 30 secs OFF for 5 cycles. For RNA-seq, 1.5 ml meiotic culture was taken at the 3-hr time point and RNA was extracted from mechanically lysed cells using the Qiagen RNeasy RNA isolation Kit and mRNA was extracted using Sera-Mag oligo-dT beads and fragmented. For MNase-seq and ChIP-seq, libraries were prepared by PCR amplification with TruSeq adaptors (Illumina) as described in (Sun et al., 2015). For RNA-seq, libraries were prepared according to the Illumina TruSeq Stranded mRNA sample preparation kit, and sequencing libraries were prepared by PCR from the cDNA samples after ligation of adapters. Quality of all libraries was checked on 2200 Tapestation or Agilent 2100 Bioanalyzer. Libraries were quantified using qPCR. The libraries were sequenced on Illumina HiSeq 2500 or NextSeq 500 instruments at NYU Biology Genomics core to yield 50 or 51 bp single-end reads or 100 bp single-end reads.
