ARA-290, also catalogued as cibinetide, is an 11-amino-acid peptide whose sequence is drawn from the helix B domain of erythropoietin. It is characterized against a heteromeric receptor comprising the erythropoietin receptor together with the beta common receptor subunit, rather than against the classical erythropoietin receptor alone.
It reproduces a short structural region of the much larger erythropoietin glycoprotein. ARA-290 is a peptide fragment by design and is not erythropoietin itself.
ARA-290 from HEEZ Research is independently tested by an accredited third-party laboratory using HPLC for purity and mass spectrometry for identity. Every peptide we supply is over 99% pure. Certificates of Analysis are published on the product page as testing is completed — review the report before you order. A certificate records the identity, purity and quantity measured for the material supplied, so you can confirm what you received matches what was ordered.
Sealed lyophilized ARA-290 vials are stable at ambient temperature in transit and ship without cold packaging. On arrival, store the sealed vial per the storage conditions on its certificate of analysis.

About ARA-290
What is ARA-290 peptide?
ARA-290 peptide (cibinetide) is a synthetic 11-amino-acid linear peptide derived from helix B of EPO — the segment that contacts the β-common receptor rather than the classical EPO receptor — supplied by HEEZ Research as a lyophilized powder for in vitro laboratory use. It is linear and non-glycosylated.
How does ARA-290 work?
In vitro, ARA-290 shows no activity at the EPO receptor and is characterized at the β-common receptor; it isolates the helix-B surface as a standalone sequence, which is its defining research feature, and it has a short half-life in assay media.
How HEEZ tests ARA-290
Solid-phase synthesis, reversed-phase purification, lyophilization.
