Quality Control

Our Vmp21 Antigen is produced under stringent quality management systems to ensure batch-to-batch consistency and high biological activity. Each lot undergoes comprehensive analytical testing, including purity assessment by HPLC and identity confirmation. A Certificate of Analysis (COA) detailing specific test results is provided with every shipment to support your regulatory and research 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 before opening to minimize moisture uptake. For extended storage, consider aliquoting to avoid repeated freeze-thaw cycles.
