ARA-290 16mg, also known as cibinetide, is an 11-amino-acid peptide derived from erythropoietin, offered by Peptide Sciences for neuro-protection and inflammation research.
ARA-290 and the Innate Repair Receptor
ARA-290 mimics the helix-B surface of erythropoietin (EPO). It binds the innate repair receptor, a heterocomplex of the EPO receptor and the beta common receptor (CD131), without stimulating red-blood-cell production. Research has focused on small-fibre neuropathy models, inflammation signalling and tissue protection after injury, making it a useful tool for separating EPO’s protective effects from its haematopoietic effects.
