Lab Testing & Quality Assurance
Every peptide we offer undergoes rigorous third-party analytical testing to ensure the highest purity and identity standards.
Our Testing Protocol
AminoCore Research maintains a multi-step quality assurance pipeline for every production batch. No product is released until all analytical criteria are met and documented.
HPLC Analysis
High-Performance Liquid Chromatography is the gold standard for peptide purity assessment. Every batch is tested via reverse-phase HPLC-UV to confirm ≥98% purity. Chromatograms are included in each Certificate of Analysis.
- C18 column reverse-phase separation
- UV detection at 214nm and 280nm
- Retention time matching against reference standards
- Area-under-curve purity calculation
Mass Spectrometry (MS)
Electrospray ionization mass spectrometry (ESI-MS) confirms molecular identity by verifying the observed molecular weight matches the theoretical mass. This ensures the correct peptide sequence was synthesized.
- ESI-MS molecular weight confirmation
- MALDI-TOF for larger peptides
- Expected vs. observed mass comparison
- Charge state deconvolution
Endotoxin Testing
Limulus Amebocyte Lysate (LAL) testing screens for bacterial endotoxin contamination. All injectable-grade peptides are verified to meet endotoxin limits before release.
Sterility & Appearance
Visual inspection for proper lyophilization (white to off-white powder), correct vial labeling, seal integrity, and packaging quality.
Certificate of Analysis (COA)
Every product ships with a batch-specific COA documenting:
- Product identity — name, catalog number, lot number
- Purity — HPLC chromatogram with ≥98% area under curve
- Molecular weight — MS-confirmed observed mass vs. expected
- Appearance — physical form description
- Storage conditions — recommended storage parameters
- Manufacture date — production and testing dates
COAs are available for download from individual product pages or upon request via our contact form.
Third-Party Verification
AminoCore Research uses independent, accredited third-party laboratories for analytical testing. This ensures objectivity and eliminates potential conflicts of interest in quality reporting. Our testing partners maintain ISO 17025 accreditation for chemical analysis.
Storage & Handling Standards
From synthesis to delivery, our cold-chain management ensures product integrity:
- Synthesis — GMP-grade raw materials, controlled environment
- Storage — -20°C freezer storage, humidity-controlled
- Packaging — Sealed vials, desiccant-protected, light-resistant
- Shipping — Insulated packaging with cold packs for temperature-sensitive products
