Six stages.
Nothing ships without them.
Every Vertalis batch passes a documented six-stage quality pipeline before it reaches your lab. No exceptions. No batch-skipping. No shortcuts.
From raw material to your bench.
Sourcing
All raw materials are procured exclusively from vetted synthesis partners operating under strict NDAs. Every supplier undergoes facility audit and documented chain-of-custody verification before we accept a single gram of material.
Synthesis
Peptides are synthesized via solid-phase peptide synthesis (SPPS) in ISO-controlled cleanroom environments. Sequence fidelity is verified at synthesis before lyophilization.
Internal QC
Each batch undergoes internal quality control including visual inspection, moisture content (Karl Fischer), and preliminary identity screen before being submitted for external testing.
Independent Testing
Every lot is independently analyzed by our third-party laboratory partners using HPLC-UV, LC-MS/MS, and LAL endotoxin assay. Results are not released internally before testing clears.
COA Publication
Certificates of Analysis are published publicly and indexed by batch code the moment they pass all thresholds. No batch ships before its COA is live.
Ambient Dispatch
Vials are sealed in inert atmosphere and dispatched via standard courier within 24h of payment confirmation. Lyophilized peptides are shelf-stable at ambient temperature, so no cold-chain packaging or ice packs are required.
What every COA covers.
HPLC Purity
High-performance liquid chromatography confirms purity ≥99.0%. Full chromatogram published in every COA.
LC-MS/MS Identity
Liquid chromatography–mass spectrometry confirms molecular weight and sequence identity against theoretical values.
Endotoxin (LAL)
Limulus Amebocyte Lysate assay confirms endotoxin levels below 5 EU/mg. Critical for in vitro research integrity.
Microbial Limits
Microbial contamination screening ensures sterility for research applications requiring clean environments.
The labs behind every COA.
We work exclusively with accredited, internationally recognized analytical laboratories. All are independent. They report results to us, not the other way around.
