ARA-290

ARA-290 is an 11-amino-acid peptide that mimics the spatial structure of part of erythropoietin (EPO). It activates the tissue-protective receptor formed by the EPO receptor and CD131 without stimulating blood formation, and is studied in inflammation and neuropathy research.

FAQ about ARA-290

How should ARA-290 be stored?

−20 °C, dry and protected from light; 2–8 °C after reconstitution. The storage note applies to the sealed product; see "Storage & handling" for details.

What is ARA-290 dissolved in in the lab?

Lyophilized peptides are usually reconstituted in the lab with bacteriostatic water (BAC water) or sterile water. Calculate the resulting concentration with our peptide calculator. We give no dosing information.

Is there a lab report for ARA-290?

Yes. The current batch C201 was tested by Janoshik on 22/06/2026: HPLC purity 99.614 %. Open the full report above under batches or in the lab report archive.

How fast is ARA-290 delivered?

We ship within 24–48 hours of payment. DHL delivers to Germany in 1–2 working days, to the rest of the EU in 2–6.

Is ARA-290 intended for use in humans?

No. All products are intended exclusively for research and laboratory purposes and not for use in humans or animals.

Research profile

What is ARA-290?

ARA-290 (pE-EQLERALNSS, 1,257.3 g/mol), also called cibinetide, mimics helix B of erythropoietin. EPO acts through two receptor forms: the homodimeric EPO receptor drives red blood cell formation, while a complex of EPO receptor and the β-common receptor CD131 mediates tissue protection. ARA-290 targets only the second.

Research status

Studies examine anti-inflammatory and tissue-protective effects, especially in small-fibre neuropathy models, with small early clinical trials. Confirmation in large trials is pending.

Status

Not approved in the EU. Research use only.
