Fig. 2. (A) Basic design of the PNA HCR and structures of γ-modified PNA backbones used in this study. (B) 5% PAGE analysis of the HCR using FITC-labelled γ-serine modified-PNAs. Conditions for the reaction: pH 7.5 0.1× PBS, 0.02% tween-20, 1 μM of each component, 20 μL, r.t., and 2 h of incubation. (C) SDS-PAGE analysis of the HCR using γ-serine modified-PNAs, BCy3serI, serH1, and serH2. Conditions for the reaction: pH 7.5 0.1× PBS, 0.02% tween-20, 1 μM of each component, 15 μL, r.t., and 3 h of incubation.
