About the Lab

Synthesis is
Verification.

SilverZone Labs supplies reference-grade peptides for academic, pharmaceutical, and analytical research. Every compound is synthesized via solid-phase peptide synthesis, purified via reverse-phase HPLC, and confirmed by mass spectrometry. Each shipment includes the lot-specific Certificate of Analysis from an independent third-party laboratory.

Contact the Lab
All compounds ship as lyophilized (freeze-dried) powder, sealed under vacuum in amber-glass vials. Each vial includes the lot number, fill mass, and synthesis date on the label.
Each lot is analyzed via reverse-phase HPLC at 220 nm and confirmed by ESI mass spectrometry. The Certificate of Analysis lists the chromatogram, mass spectrum, and percent purity by area integration.
The COA is a third-party-issued document that records the lot-specific test data: HPLC purity, mass-spec confirmation, peptide content (gravimetric), water content, and counter-ion content where applicable. SilverZone Labs attaches the COA to every shipment and hosts it for download via the lot number.
Lyophilized peptides should be stored at -20°C, protected from light and moisture. Once reconstituted in an appropriate aqueous diluent for downstream assays, store at 2-8°C and discard per your lab's SOP. Avoid repeated freeze-thaw cycles.
Yes. Email the lab with the compound name and quantity and we will send the most recent lot's COA. Lot-specific COAs are also available post-purchase via the order confirmation.
The minimum specification is ≥99.0% purity by HPLC. The specification is what the product is offered against; the measured result for the lot you receive is stated on that lot-specific Certificate of Analysis.
Domestic US shipments dispatch within 48 hours. International shipments are handled case-by-case — contact the lab for a quote and customs documentation.
