What the Bench Looked Like Before AutomationChemists who entered peptide synthesis in the 1990s and early 2000s often describe a workflow built on patience and repetition. Solid-phase peptide synthesis required manual coupling steps, careful timing, and constant attention to reaction vessels that had to be monitored by hand. Peptide research laboratories benefit from this same culture of standardization, even when their specific reference materials come from specialized sources. A Toolkit Built on ContinuityWhat stands out most in conversations with chemists who have spent decades in peptide research is how little nostalgia shapes their view of the changes. The instruments changed.
