Quality Control

Our Iturin A-3 is produced and tested under strict quality management protocols to ensure high purity and batch-to-batch consistency. Each lot is characterized using advanced analytical techniques, including HPLC and mass spectrometry, to confirm identity and potency. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and related substances is provided with every shipment to support your research and quality assurance requirements.

Storage

Preserve in a tightly closed container, protected from light. Store at 2-8°C in a dry environment. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed under desiccant or inert atmosphere after opening to prevent degradation.
