ARA-290 (Cibinetide) is an 11-amino-acid peptide derived from the helix-B domain of erythropoietin, studied for tissue protection and neuropathic pain in research models without erythropoietic activity.
For laboratory and research use only. Not for human or veterinary use.
Activates the innate repair receptor (IRR), a heteromer of EPO receptor and CD131, triggering anti-inflammatory and tissue-protective pathways without stimulating red blood cell production.
