Scrambled sequence, the negative control for nonspecific binding. (A) Predicted secondary structures of unbound miR-34a (pink) and unbound scrambled control (scrm, black) using MC-Fold (23). (B) Normalized reactivity of the scrm control inserted in the unbound trans-scaffold (gray), bound by miR-34a (red) and miR-34a loaded AGO2 with respective heatmaps in C, indicating that no unspecific interactions with the RNA or the RNA-RBP complex occur.
