Quality Control

Our L-Glutamic Acid-L-Tyrosine Copolymer is manufactured under a strict quality management system. Each batch is characterized to ensure consistency in molecular weight distribution, amino acid composition, and impurity profile. We provide comprehensive Certificates of Analysis (COA) with data for key parameters such as assay, residual solvents, and endotoxin levels where applicable, supporting its use in research and cGMP-guided development.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); ensure the container is sealed after each use to prevent absorption of atmospheric moisture.
