Quality Control

Our Pseudin-2 is produced and analyzed under stringent quality management protocols to ensure batch-to-batch consistency and reliability for research purposes. Each lot is accompanied by a comprehensive Certificate of Analysis (COA) detailing purity, identity, and other critical parameters. We adhere to high-purity standards typical for research-grade peptides, ensuring suitability for sensitive biological assays.

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 minimize moisture uptake. For long-term storage, consider under an inert atmosphere.
