PRJDA63201 The analysis of the phosphorylation of Ser2/Ser5/Ser7 residue of RNAP2 in Hela cells We originally generated monoclonal antibodies which specifically react with Ser2 , Ser7 or Ser5 residue of the C-terminal domain of RNA polymerase 2. The genome wide recruitment of Ser5P, S7P and/or Ser2P RNA polymerase 2 was evaluated in Hela cells.
