Figure 1. The purity of the synthesized peptides. A: A typical RP-HPLC elution profile of the purified keratin10 (330–341) peptide. B: Mass analysis of the purified keratin10 (330–341) peptide. The observed mass of the keratin10 (330–341) peptide is consistent with the theoretical mass. The purity of the peptide was confirmed to be more than 99%. The purities of all synthesized peptides were confirmed by a combination of RP-HPLC and mass analysis.
