Quality Control

Our synthetic peptides are manufactured under strict quality control protocols to ensure the highest standards of purity and identity. Each batch is characterized using advanced analytical techniques including HPLC for purity assessment and Mass Spectrometry (MS) for confirmation of molecular weight and sequence. Certificates of Analysis (COA) detailing purity, analytical data, and storage recommendations are provided with every shipment and are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below in a freezer. This product is hygroscopic (moisture-sensitive). For long-term storage, it is recommended to store the lyophilized powder under desiccant. Aliquot reconstituted solutions to avoid repeated freeze-thaw cycles.
