ARA-290 – Research Peptide
ARA-290 (also known as cibinetide) is a synthetic 11-amino-acid research peptide supplied as a high-purity lyophilised powder for laboratory use. It is derived from the helix B surface region of erythropoietin (EPO) and is described in the literature as a selective ligand of the innate repair receptor (IRR), without the erythropoietic activity associated with EPO itself.
ARA-290 is commonly examined in preclinical studies of tissue protection, inflammatory signalling and peripheral nerve models. Zentra Labs supplies this material with batch-specific purity documentation and a Certificate of Analysis (COA) so researchers can review the analytical data before experimental use.
For research use only. Not intended for human consumption, medical, therapeutic, diagnostic, or veterinary use.

Research Background
In laboratory and preclinical research settings, ARA-290 is commonly investigated in studies involving:
- Innate repair receptor (EPOR/CD131 heteromer) signalling
- Tissue-protective and cytoprotective pathway models
- Inflammatory cytokine signalling, often alongside peptides such as KPV
- Peripheral nerve and small-fibre neuropathy models
- Tissue repair research, where it is sometimes compared with BPC-157
Researchers looking for a reliable ARA-290 research supplier typically prioritise independent analytical data and clear batch-specific Certificates of Analysis. Our guide on how to verify a peptide Certificate of Analysis is genuine explains what to look for. For published studies, recognised databases such as PubMed can be consulted.
Handling & Storage
- Reconstitute according to laboratory protocols (commonly with bacteriostatic water or sterile water)
- Gently swirl until fully dissolved – do not shake
- Use only within controlled research environments
- Store lyophilised material in a cool, dry place away from light (long-term storage at −20°C or below recommended)
- After reconstitution, refrigerate at 2–8°C
- Avoid repeated freeze-thaw cycles
Storage and reconstitution requirements can vary. Always refer to the product-specific or batch-specific documentation supplied with the material and follow your institutional laboratory protocols.
