Manufacturing & SPPS
QSC's Qingdao facility produces peptides through a multi-stage pipeline from raw amino acids to finished lyophilized product.
Production Pipeline
| Stage | Process |
|---|---|
| 1. Synthesis | Automated SPPS (solid-phase peptide synthesis) |
| 2. Cleavage | Release crude peptide from resin support |
| 3. Purification | Preparative HPLC to ≥99% |
| 4. Verification | Mass spectrometry molecular identity |
| 5. Lyophilization | Freeze-drying for stability and shipping |
| 6. QC | Janoshik independent COA verification |
