Quality Control

Our Biotin-Teg Cep is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity verification and structural confirmation by NMR and mass spectrometry, to ensure it meets the high standards required for research and bioconjugation applications. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 2-8°C (refrigerated) or as indicated on the label or COA. This product is hygroscopic (moisture-sensitive). Allow the sealed vial to equilibrate to room temperature before opening to minimize moisture absorption.
