Quality Control

Our Poly 18 Antigen is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity, MS for identity confirmation, and functional validation in relevant assay systems. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing all specifications and test results to ensure traceability and compliance with your quality requirements.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below for long-term stability. This product is hygroscopic (moisture-sensitive); allow the vial to equilibrate to room temperature in a desiccator before opening to prevent condensation and moisture uptake.
