Quality Control

Every batch of Callitachykinin Ii is manufactured and tested under strict quality management systems to ensure the highest standards of purity and consistency for research applications. Our products undergo rigorous analytical testing, including reversed-phase HPLC and mass spectrometry. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and peptide content is provided with each shipment to guarantee traceability and reliability for your critical work.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below in a dedicated freezer. This product is hygroscopic (moisture-sensitive). Allow the vial to equilibrate to room temperature in a desiccator before opening to prevent condensation and moisture uptake. For long-term storage, consider storing under an inert atmosphere.
