§03 · VERIFICATION
Every vial, independently verified.
Each batch is synthesized in our audited US facility, lyophilized under vacuum, and submitted to an independent third-party laboratory for HPLC and MS quantification before any unit enters the shipping queue.
01
Synthesis
USA · AUDITED FACILITYSolid-phase peptide synthesis under cleanroom protocol. Each crude product is logged against a unique lot identifier — IL-YYWW-xxxN.
02
Lyophilization
VACUUM-DRIED · SEALED AMBER GLASSDried under vacuum, sealed in amber glass under inert gas. Vials are stable at -20°C and labeled with lot, mass, and synthesis date.
03
Independent assay
HPLC + MS · THIRD-PARTYA representative sample from every lot is HPLC purity-quantified and MS molecular-weight-confirmed by a contract analytical lab.
04
COA release
BATCH-LINKED PDFA signed certificate is bound to the lot identifier and made available for download from the verification archive before shipping begins.
