01 / DESIGN
What was studied?
Three surface-functionalization chemistries were compared using model peptide synthesis and surface and mass-spectrometric measurements.
02 / FINDINGS
What did the researchers report?
Surface resilience and product purity did not follow the same simple ranking. Capping unreacted sites improved selected purity measurements.
03 / LIMITS
How should it be interpreted?
A more stable synthesis support does not necessarily produce a purer peptide. Findings concern specific surface-supported methods rather than ordinary vial quality or supplier certification.
