A research peptide passes through at least six operations between a resin bead and a purchaser's hand: solid-phase synthesis, cleavage from the resin, preparative purification, lyophilisation, filling and closure, and freight — frequently followed by a period in a regional warehouse and, in some arrangements, by repackaging.[1]
Each operation has a characteristic failure mode, and the great majority of quality observations made downstream are attributable to one of them rather than to a general property of the material or the seller.[2] Knowing which stage produces which observation is what allows a purchaser to read a certificate as evidence about something rather than as a number.
