- Amino-Acid Sequence
- Ala-Glu-Asp (A-E-D)
- Mass spectrometry confirms molecular weight 277.23 g/mol
- Structurally identical—name reflects sourcing tradition, not chemical difference
- Synthesis Method
- Solid-phase peptide synthesis (SPPS) using Fmoc chemistry
- HPLC chromatogram shows single peak at expected retention time
- Synthesis pathway is standardised across suppliers—purity depends on post-synthesis purification rigor
- Typical Purity (HPLC)
- ≥95% (research-grade), ≥98% (pharmaceutical-grade)
- HPLC with UV detection at 214 nm; certificate of analysis (CoA) from supplier
- Demand CoA with batch-specific purity data—generic spec sheets insufficient
- Reconstitution Protocol
- 1–2 mg per mL bacteriostatic water or sterile saline
- Visual inspection (clear, colourless solution indicates proper dissolution)
- Reconstitution stability identical—store at 2–8°C, use within 28 days
- Primary Research Use
- Cartilage regeneration, osteoarthritis models, connective tissue repair
- Confirm tissue tropism through published literature referencing amino-acid sequence
- Both designations target the same biological pathways—choose based on supplier reliability, not name
- Regulatory Status
- Not FDA-approved for human use; research compound only
- Verify supplier operates as 503B facility or holds appropriate research chemical license
- Both are research-grade compounds—neither is a drug product approved for clinical use
