Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below for long-term stability. This hygroscopic (moisture-sensitive) peptide should be kept in a cool, dry place and allowed to equilibrate to room temperature in a desiccator before opening to prevent condensation and hydrolysis. For extended storage, consider under an inert atmosphere.
