RP-HPLC chromatogram (14–50% acetonitrile/0.1% TFA gradient) of C-terminal-Dbz H4 peptide without Alloc protection. C-terminal AA introduced as A) Fmoc-Gly-OH and B) Fmoc-(Dmb)Gly-OH. Peptide identities were confirmed by MALDI-TOF MS analysis; for full product analysis see Supplemental Table T1. Desired product H4C-C0 : [M+H]+ observed m/z 1060.4, expected m/z 1060.5; Major branched product H4C-C1 : [M+H]+ observed m/z 1969.1, expected m/z 1969.0.
