Sperms were released from the cauda epididymides of adult male mice and collected by swim-up method. For the 3a/3L DM sperm, viable sperms were selected by mouth pipetting Sample with unmethylated lambda phage DNA was subjected to bisulfite treatment and library construction by the post-bisulfite adaptor tagging (PBAT) method (Miura et al., 2012).
