Quality Control

Our Bs2G Crosslinker is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the high standards required for sensitive bioconjugation and pharmaceutical applications. Certificates of Analysis (COA) documenting batch-specific results are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 2-8°C. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed under desiccant and allowed to equilibrate to room temperature before opening to prevent condensation.
