Ara-290 definition
ARA-290 (cibinetide) is an 11-amino-acid synthetic peptide derived from the helix-B surface of erythropoietin. Research models have examined its interaction with the innate-repair receptor (IRR; CD131 / β-common subunit) without engaging classical erythropoietin receptors. The compound is studied in preclinical tissue-protection research without erythropoiesis side effects characteristic of EPO. Research use only. Supplied by Nexus Laboratory with batch-level certificate of analysis documenting HPLC purity, mass spectrometry identity, and endotoxin screening.
