ARA-290 (Cibinetide) — 11-amino-acid peptide research compound derived from erythropoietin's tissue-protective domain.

ARA-290 (Cibinetide) is an 11-amino-acid peptide research compound derived from the helix B region of erythropoietin (EPO) — the part responsible for EPO’s tissue-protective effects without the hematopoietic activity.
ARA-290 binds the Innate Repair Receptor (IRR) — a heterocomplex of EPO receptor and CD131. This receptor is expressed in injured tissues and not normal tissues, making ARA-290 of particular research interest for site-specific cellular protection.
Used in: neurotrophic research, peripheral nerve research models, sarcoidosis research, comparative EPO-derivative studies.
