Research FAQ
Detailed information regarding product handling, storage, and laboratory protocols.
Yes, all peptides are in lyophilized powder form to ensure maximum stability and shelf-life. They must be reconstituted with bacteriostatic water prior to research use.
Lyophilized (powder) peptides should be stored in a cool, dark place. For long-term stability, we recommend refrigeration (2°C – 8°C) or freezing (-20°C). Once reconstituted, peptides must be refrigerated.
