Quality Control

Our n-Acetyl-D-Galactosamine-Pap-Hsa is produced under stringent quality management protocols. Each batch undergoes rigorous analytical testing to ensure identity, purity, and conjugate integrity, meeting the exacting standards required for research and development applications. A comprehensive Certificate of Analysis (COA) detailing purity, biological activity (where applicable), and other critical parameters is provided with every shipment.

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. For short-term use, store at 2-8°C.
