About USA Peptide Depot
Supplying HPLC-tested research peptides and reference materials to academic universities, private laboratories, and biotechnology institutions.
Uncompromising Chemical Integrity
USA Peptide Depot was founded to eliminate the variance and lack of transparency historically associated with research chemical procurement. We believe researchers deserve clear, reproducible purity data before running critical in-vitro assays.
Every peptide batch we distribute is synthesized via automated solid-phase peptide synthesis (SPPS), purified with preparative RP-HPLC, lyophilized into sterile Type I borosilicate vials under inert argon atmosphere, and validated through independent third-party laboratories.
Our Laboratory Guarantees
- Guaranteed Purity: Minimum 99.0% chromatographic purity on every peptide.
- Full Analytical Transparency: Publicly verifiable RP-HPLC UV-214nm chromatograms and MS spectra.
- USA Domestic Operations: Climate-controlled warehousing and expedited same-day dispatch.
Automated SPPS Synthesis
Solid-phase peptide synthesis utilizing Fmoc chemistry ensuring precise amino acid chain sequencing and minimizing deletion impurities.
Independent 3rd-Party Audits
Analytical validation conducted by recognized independent facilities including Janoshik Analytical and MZ Biolabs.
Cold-Chain Delivery
Protective thermal insulated packaging ensuring lyophilized peptide stability during domestic transit.
