As an accredited Protein Polypeptides factory, we enforce strict quality protocols—every batch undergoes rigorous testing to ensure consistent efficacy and safety standards.
| Packing | Protein Polypeptides, 100g: Sealed amber glass bottle with tamper-evident cap and clear labeling for laboratory use. Store in cool, dry place. |
| Storage | Protein polypeptides should be stored in tightly sealed containers to prevent moisture absorption and contamination. They are typically kept at -20°C or lower for long-term storage, or 2–8°C for short-term use. Protect from light and repeated freeze-thaw cycles, as these can degrade the protein. Always follow the supplier’s guidelines for optimal stability and performance. |
| Shipping | Protein Polypeptides are shipped in tightly sealed, labeled containers under cool, dry conditions to prevent degradation. Shipments typically require insulated packaging, sometimes with ice packs or refrigeration, depending on stability. Proper documentation, including Safety Data Sheets (SDS), accompanies the shipment to ensure compliance with relevant chemical transport regulations and safety standards. |
