Quality Control

Our Neosulfakinin I is manufactured under strict quality protocols to ensure batch-to-batch consistency and high biological activity. Each lot is supported by a comprehensive Certificate of Analysis (COA) detailing purity, identity, and peptide content. We adhere to GMP principles for research-grade biochemicals, and specifications are designed to meet the rigorous demands of pharmaceutical and agrochemical R&D.

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 under an inert atmosphere.
