Quality Control

Our Deoxyribonucleic Acid Sodium Salt From Salmon Testes is produced under strict quality management protocols. Each batch is tested to ensure high purity, appropriate molecular weight distribution, and consistent performance. We provide comprehensive Certificates of Analysis (COA) detailing parameters such as absorbance ratios (A260/A280), protein content, and enzymatic digestibility. Our quality system is designed to meet the rigorous demands of research and development applications.

Storage

Preserve in a tightly closed container, protected from light. Store at 2-8°C. The product is hygroscopic (moisture-sensitive); ensure the container is sealed tightly after each use to prevent absorption of atmospheric moisture. For long-term stability, consider storage at -20°C.
