Quality Control

Our Callosin is produced under a strict quality management system to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including identification, assay, and impurity profiling. Certificates of Analysis (COA) documenting full specifications are provided with every shipment. We can support development projects with material meeting research-grade to GMP-grade standards as required.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (typically 15-25°C). This material is hygroscopic (moisture-sensitive) and should be handled under dry conditions to maintain stability.
