library_construction_protocol: ChIP-seq: Cells were first crosslinked by formaldehyde, then sonicated in SDS containing buffer to dissolve the chromatin. The clarified chromatin were immunoprecipitated with dyno beas conjucated with antibodies. For ChOR-seq, EdU pulse labeled DNA was biotinylated by Click Reaction, then  chromatin were  immunoprecipitated with streptavidin dyno beads( Invitrogent, M280).The ChIP-seq antibodies are as following: Anti-H3K27me3,GST, 9733S;Anti-V5,Gene-Protein Link,P01L075 ChIP-seq: H3K27me3 were prepared according to NEBNext Ultra DNA Library Prep Kit for Illumina (E7370L) and were sequenced using Nova seq.
