Figure 6. Blocking peptide experiments for pARS578 are shown.

The top row represents the positive control i.e. IHC conducted with each AR phosphospecific antibody as indicated. The bottom row represents antibodies to AR phosphorylation sites pre-incubated with pAR^S578 peptide. The specific peptide utilised is boxed in red. No staining is demonstrated when the pAR^S578 peptide is incubated with pAR^S578antibody, whereas staining is maintained at the other phospho-AR sites.
