ARA-290 (Cibinetide) Lyophilized Peptide
ARA-290, also called cibinetide, is an 11–amino acid peptide derived from the structure of erythropoietin (EPO). It was designed to engage the innate repair receptor without stimulating red blood cell production, and is offered here in 10mg, 16mg, and 50mg lyophilized vials.
Research Applications
Researchers use ARA-290 to study the innate repair receptor (a complex of the EPO receptor and the β-common receptor) and its role in tissue protection. Lab models focus on inflammatory signaling, nerve fiber biology, and cytoprotective pathways.
Why Researchers Choose It
- Non-erythropoietic EPO-derived research peptide
- Three sizes for flexible study planning
- Lyophilized for stability in storage and transit
- Batch-tracked with third-party COA testing

Frequently Asked Questions
What is the difference between ARA-290 and EPO?
ARA-290 is a short peptide based on part of EPO’s structure. It is studied for tissue-protective signaling without EPO’s effect on red blood cell production.
Is ARA-290 the same as cibinetide?
Yes. Cibinetide is the non-proprietary name for ARA-290.
Does this product come with a Certificate of Analysis?
Yes. Every batch is supported by independent third-party analytical testing confirming identity and purity.
What does lyophilized mean?
Lyophilized means freeze-dried. Removing water this way gives the peptide a stable powder form that holds up well in storage and shipping.
Is this product approved for human or animal use?
No. It is sold strictly for in-vitro laboratory research.
