WebThe Fmoc-based PNA synthesis route consists of repeated cycles of deprotection, activation, coupling and capping, as shown in Figure 2. The direction of synthesis is from the C terminal (carboxyl terminal) to the N terminal (amino terminal). WebGamma PNA has a stereogenic center at the γ-carbon atom of the N-aminoethyl glycine unit. γ-substituted PNA can be placed in every third residue of regular PNA. Tm of gamma PNA is higher by 5~8 ℃ per single substitution, which results …
