Oligonucleotide manufacturing does not fail at a single point – it fails at the seams between stages. This article examines the integrated supply chain from raw material sourcing through drug substance synthesis (SPOS or enzymatic ligation), purification, bioconjugation, and drug product formation, highlighting how upstream constraints in reagent supply and GMP capacity propagate downstream to affect timelines, technology selection, and commercial launch readiness.
