After transferring the Sub1 Flag plasmid into HL-1 cells, the cells were treated with bleomycin for 24 hours, followed by immunoprecipitation using Flag magnetic beads and protein mass spectrometry.
liquid chromatography tandem mass spectrometry is used to identificate of the circEZH2_005-Interacting protein pulled down by circEZH2_005 junction probe with protein extracts from Intestinal crypt cells.
