Quality assurance framework

RP-HPLC Purity Analysis

Every lot is analyzed using reversed-phase high-performance liquid chromatography (RP-HPLC) by Kovera Labs, an independent third-party laboratory. Purity is determined by peak area integration, with all lots verified to ≥98% purity.

Full UV chromatograms (220 nm and 280 nm) are included in every Certificate of Analysis, allowing researchers to verify peak purity and detect potential impurities or degradation products.

Third-Party Certificates

We partner with independent third-party analytical laboratories for verification. Certificates of Analysis include batch-specific data: lot number, synthesis date, expiration date, storage recommendations, and full analytical traces. Lot-level traceability is maintained for research recordkeeping requirements.

CoAs are provided as downloadable PDFs for each product. Lot-specific certificates are available upon request.

Controlled Analytical Production

All peptides are synthesized via solid-phase peptide synthesis (SPPS) using Fmoc chemistry under controlled analytical practices consistent with research-reagent production. Synthesis is followed by preparative HPLC purification to ≥98% purity. Final products are lyophilized (freeze-dried), packaged in amber glass vials, and sealed under inert atmosphere (argon or nitrogen).

Research-Grade Logistics

Tracked courier delivery in protective packaging. Lyophilized peptides are shelf-stable at ambient temperature for 30+ days — refrigeration during transit is unnecessary for the lyophilized form. Upon receipt, researchers store at 2-8°C (medium-term) or -20°C (long-term).
