... the control. The level of CP2 expression in each group of cells was confirmed by Western blotting, an example of which is shown (bottom panel). Expression of b-tubulin was used as a loading control. ... presence of CP2 in the protein–DNA complex was verified by adding CP2 antibody. Addition of the CP2 antibody supershifted a portion of the CP2 com- plex (lane 6), but use of...
