(A) Representative pictures of nascent Camk2a-peptides in mock- and PTX-treated neurons. Upper Panels: Representative overview images with merged channels (grey: MAP2-staining, red: Duolink-PLA signal, blue: Hoechst nuclear staining). Middle Panels: Magnifications of boxed areas marked in (A). MAP2 signal was used to outline somata and dendritic processes (white lines). Lower Panels: Negative control of puromycin-untreated cells with representative Duolink-signal in dendrite and soma, respectively. (Scale bars: in overview images 20 μm, in inserts of higher magnification 5 μm). (B) Same as A with nascent Synapsin1-peptides. (
