(A) Example of a positive control brain section obtained for all 14-3-3 isoforms except for 14-3-3 σ. (B) Skin positive control for 14-3-3 σ. (C) Example of a negative control section with no primary antibody obtained for all isoforms. (D) Example of a negative control with rabbit serum in place of primary antibody obtained for all isoforms. All scale bars indicate 100 μm.
