Frequently Asked Questions
Peptides are short chains of amino acids — the building blocks of proteins. In the lab they're studied for their role in cell signaling and research. Everything we sell is supplied strictly for research use.
It depends on the vial and the concentration your protocol requires. A common starting point is 1–2 mL of bacteriostatic water per vial — adjust to reach your target concentration and follow your lab's procedures.
Add the bacteriostatic water slowly, letting it run down the inside wall of the vial rather than onto the powder. Don't shake — swirl gently until fully dissolved, working under clean laboratory conditions.
Sealed, lyophilized peptides stay stable for a long time when frozen and kept dry. Once reconstituted, they're generally used within a few weeks under refrigeration. Exact shelf life varies by peptide and storage.
Keep unopened, powdered vials in the freezer, away from light and moisture. Store reconstituted peptides in the refrigerator and avoid repeated freeze–thaw cycles. Always follow the guidance for your specific product.
