ARA-290
An 11-amino-acid sequence derived from the B-helix of erythropoietin. Studied in tissue and neural research.
What is tested, and what each test answers
Every batch runs the full panel. Nothing ships on a partial result.
- HPLC
- PuritySeparates everything in the sample. One compound, one peak. That peak measured against everything else is the purity figure.
- LC-MS
- IdentityWeighs the molecule. Every peptide sequence has a mass nothing else shares — this confirms the vial holds the compound on the label.
- Net peptide content
- QuantityWhat the vial actually weighs out at, against the stated amount. A vial can be perfectly pure and still be short.
- Endotoxin
- ContaminationFragments of bacterial cell wall left over from manufacture. They survive sterilisation and a purity test does not see them.
Certificate of Analysis
Published, not promised.
The first production batch of ARA-290 is still being certified. Its certificate is published the moment it is released — we post each one as it comes back from the laboratory, never before.
Certificates are published on the Verification page and are viewable with a free research account. They are never emailed, and there is no code on the vial.
