Quality Control

Our peptide building blocks are produced under stringent quality protocols to ensure high purity and batch-to-batch consistency. Each lot undergoes comprehensive analytical characterization, including HPLC, MS, and NMR, to confirm identity and purity. Certificates of Analysis (COA) detailing all specifications are provided with every shipment. We support research and development needs with materials suitable for laboratory use and can discuss GMP-grade manufacturing for advanced clinical applications.

Storage

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