Instrument: Illumina HiSeq 2500
Strategy: Bisulfite-Seq
Source: GENOMIC
Selection: RANDOM
Layout: PAIRED
Construction protocol: single cell or small amounts of cells were seeded into the lysis buffer using the mouth pipette, and DNAs were released after proteinase treatment at 50C and then bisulfite converted. After purification, DNAs were complemented with the biotinated random primer (5’-biotin-CTACACGACGCTCTTCCGATCTNNNNNNNNN-3’) and 50 units of klenow polymerase (3’ to 5’exo-, New England Biolabs). This random priming was repeated 5 times in total. The second strands were synthesized using another random primer (5’-AGACGTGTGCTCTTCCGATCTNNNNNNNNN-3’) and the final libraries were generated after 8-12 cycles PCR amplification with the Illumina universal PCR primer and Illumina indexed primer.
