4C-Seq identify the interaction between IRF8 promoter and rs2280381-containing region in human primary monocyte

To test if lncRNA AC092723.1 play a role in physical interaction between the IRF8 promoter and the rs2280381-containing region, we conducted circular chromatin conformation capture assay in the human primary monocyte. We knock down lncRNA AC092723.1 by electro-transfecting ASOs, the control group is transfected negtive ASOs with no impact on lncRNA AC092723.1.We used CSP6I as the first digested enzyme and NlaIII as the second enzyme. After constructing 4C library,we then utilize 4C-PCR primer to construct IRF8 point view 4C library.
