Quality Control

Our Immunoglobulin G (285-292) is manufactured under strict quality systems. Each batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. Certificates of Analysis (COA) are provided, detailing results from HPLC for purity, Mass Spectrometry (MS) for confirmation, and other relevant assays. We support research and development requiring high-purity peptide standards.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below in a dry environment. This peptide is hygroscopic (moisture-sensitive) and should be allowed to equilibrate to room temperature before opening to minimize condensation. For long-term storage, consider storing under an inert atmosphere to prevent oxidation.
