The Laboratory
Every vial that leaves this house is answerable to a ledger. Provenance is not a claim we make; it is a chain of custody we keep.
Three pillars, in order.
Fmoc SPPS · cleanroom
Synthesis
Solid-phase peptide synthesis on automated coupling cycles, monitored for efficiency.
Prep RP-HPLC · ≥ 99%
Purification
Preparative reversed-phase HPLC with archived method files per SKU.
LC-MS · KF · LAL
Verification
Identity by mass spec, moisture by Karl Fischer, endotoxin by Limulus amebocyte lysate.
From precursor to seal.
Raw Material
USP/EP reference precursors sourced under signed CoA. Every intake batch is logged and quarantined pending in-house verification.
Solid-Phase Synthesis
Fmoc chemistry on automated synthesizers in a controlled cleanroom. Coupling efficiency monitored per cycle.
Reversed-Phase HPLC
Preparative purification to a ≥ 99% purity floor. Method transfer files are archived for every SKU.
Lyophilization
Freeze-drying under vacuum with programmed shelf-temperature ramps. Residual moisture verified by Karl Fischer.
Certificate of Analysis
Batch identity confirmed by LC-MS. Endotoxin, bioburden, and appearance recorded. COA hashed and signed.
Cold-Chain Fulfillment
Vials stored at 2–8 °C, shipped with validated insulation. Every parcel carries a batch-linked seal.
The bench, itemized.
