| Extraction protocol |
Library construction protocol: Five µg of genomic DNA was extracted from frozen cell pellets using the DNeasy Mini Kit (Qiagen, Valencia, CA) and spiked with 25 ng unmethylated cl857 Sam7 Lambda DNA (Promega, Madison, WI). The DNA was fragmented with a Covaris S2 (Covaris, Woburn, MA) to 100-150 bp, followed by end repair and addition of a 3' A base. Cytosine-methylated adapters provided by Illumina (Illumina, San Diego, CA) were ligated to the sonicated DNA at 16degC for 16 hours with T4 DNA ligase (New England Biolabs). Adapter-ligated DNA was isolated by two rounds of purification with AMPure XP beads (Beckman Coulter Genomics, Danvers, MA). Adapter-ligated DNA (~450 ng) was subjected to sodium bisulfite conversion using the MethylCode kit (Life Technologies, Carlsbad, CA) as per manufacturer's instructions. The bisulfite-converted, adapter-ligated DNA molecules were enriched by 4 cycles of PCR with the following reaction composition: 2.5 U of uracil-insensitive PfuTurboCx Hotstart DNA polymerase (Stratagene), 5 µl 10X PfuTurbo reaction buffer, 31 µM dNTPs, 1 µl Primer 1, 1 µl Primer 2 (50 µl final). The thermocycling parameters were: 95degC 2 min, 98degC 30 sec, then 4-8 cycles of 98degC 15 sec, 60degC 30 sec and 72degC 4 min, ending with one 72degC 10 min step. The reaction products were purified using AMPure XP beads (two rounds). Up to three separate PCR reactions were performed on subsets of the adapter-ligated, bisulfite-converted DNA, yielding up to three independent libraries from the same biological sample.

ANALYSIS DESCRIPTION: Illumina Bisulfite-Seq read mappings from the iPS DF 19.11 Cell Line, Library methylC-seq_ff_ips_19_11_r2a were processed into graphs of methylation proportions. Methylation proportions were calculated as (methylated calls / (methylated calls + unmethylated calls)) for all CpGs covered by at least 4 reads. Reads from the + and - strands were combined for methylation proportion calculations.
