About
Research peptides built for reproducible science.
Peptides Lab supplies laboratories with HPLC + mass-spec verified reference compounds. Our entire workflow — synthesis, analysis, cold-chain handling — is designed around the standards your protocol depends on.
Our mission
To make analytically credible peptide reference material accessible to every research laboratory — with full batch traceability, transparent CoAs, and no compromise on purity.
Lab standards
RP-HPLC at 214 nm
Every batch quantified by reversed-phase HPLC at the peptide-bond absorption wavelength.
ESI-MS confirmation
Molecular identity verified by electrospray mass spectrometry against theoretical mass.
Third-party verification
Randomized batches sent to independent accredited analytical labs to eliminate supplier conflicts of interest.
Cold-chain logistics
Lyophilized peptides stored at -20°C and shipped in insulated thermal packaging.
Our testing process
- 1
Synthesis
Solid-phase peptide synthesis (SPPS) using Fmoc chemistry under inert atmosphere in partnered GMP facilities.
- 2
In-house QC
Every batch screened by RP-HPLC and mass spectrometry before any vial is approved for fill-and-finish.
- 3
Lyophilization
Sterile lyophilization with controlled residual moisture targets for long-term stability.
- 4
Third-party verification
Randomized vials sent to an independent accredited analytical lab. Results published on the CoA shipped with every order.
- 5
Cold-chain dispatch
Insulated packaging with phase-change materials and discreet tracked courier delivery.
