What Is ARA-290?

ARA-290 (cibinetide) is a synthetic peptide corresponding to a surface region of helix B of erythropoietin (EPO). It was designed to isolate the tissue-protective and anti-inflammatory signaling associated with EPO while removing the erythropoietic (red-blood-cell-stimulating) and thrombotic activities of the full hormone.

In experimental settings, ARA-290 is used to study signaling through the innate repair receptor, a heteromeric receptor complex distinct from the classical EPO receptor that mediates cytoprotection and tissue repair. This makes it a valuable probe for separating EPO's protective functions from its hematopoietic role in controlled models.

Present understanding derives from cell-culture assays, animal models, and translational research. Findings should be interpreted within their experimental context and not treated as established clinical outcomes. Puritide Research supplies ARA-290 strictly for laboratory use; it is not approved for human or veterinary application.
