Quality Control

Our synthetic peptides are manufactured under strict quality systems to ensure batch-to-batch consistency and traceability. Each lot of L-Proline, L-leucyl-L-glutaminyl-L-valyl-L-threonyl-L-α-aspartyl-L-serylglycyl-L-leucyl-L-tyrosyl-L-arginyl-L-cysteinyl-L-valyl-L-isoleucyl-L-tyrosyl-L-histidyl-L-prolyl- is subjected to rigorous analytical testing, including HPLC for purity and MS for identity confirmation. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment to support your quality and regulatory requirements.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below in a dry environment. For long-term storage, consider lyophilized powder under inert atmosphere. This product is hygroscopic (moisture-sensitive) and easily oxidized (store under inert atmosphere). Allow the vial to equilibrate to room temperature in a desiccator before opening to minimize moisture uptake.
