Quality Control

Every batch of G2 2Ab (500Pmol/Vial) is manufactured and tested under strict quality management systems. The product undergoes rigorous analytical characterization, including mass spectrometry (MS) for identity confirmation and high-performance liquid chromatography (HPLC) for purity assessment, to ensure it meets exacting specifications for use as a reference standard. A comprehensive Certificate of Analysis (COA) detailing identity, purity, concentration, and stability data is provided with each shipment.

Storage

Preserve in the original sealed vial within a tightly closed container, protected from light. For long-term stability, store at -20°C or below. This product is highly volatile in solution; ensure vials are kept tightly sealed at all times and allowed to equilibrate to room temperature before opening to prevent condensation. Avoid repeated freeze-thaw cycles.
