title: GSM2446503: HCC.ct-224; Homo sapiens; Bisulfite-Seq
library_construction_protocol: cfDNA extraction from 1.5 ml of serum samples was performed using QIAamp cfDNA Kit (Qiagen) according to manufacturer’s recommendations 10 ng of cfDNA was bisulfite-converted using EZ DNA Methylation-Lightning™ Kit (Zymo). Bis-DNA specific "padlock" probes (molecular inversion probes, MIPS) were used to capture genomic regions and provide adaptors for NGS library construction. Nextera-XT compatible barcoding primers were used to amplify DNA for sequencing. Library (~300bp) was purified using AMPure beads. custom-made libraries were sequenced on HiSeq2500 using 150PE reads
