ARA-290 10mg – High-Purity Cibinetide Peptide
ARA-290 (also known as Cibinetide) is a synthetic peptide derived from the helix B domain of erythropoietin (EPO). It has been structurally modified to selectively activate the innate repair receptor (IRR) without stimulating classical erythropoietic pathways. Supplied in lyophilised (freeze-dried) form to preserve molecular stability, this compound is verified at >99.1% purity (HPLC-tested) and provided with full Certificates of Analysis (COAs).
Designed as a research-grade analogue, ARA-290 is investigated in laboratory and preclinical models exploring cytoprotective and anti-inflammatory signalling mechanisms independent of red blood cell production.
What is ARA-290?
ARA-290 is an 11-amino-acid peptide engineered from the helix B surface region of erythropoietin. Unlike full-length EPO, ARA-290 selectively interacts with the EPOR-CD131 receptor complex, also referred to as the innate repair receptor (IRR), without activating pathways linked to erythropoiesis.
This selective receptor activity has made ARA-290 a subject of interest in experimental models examining tissue protection, inflammatory signalling, and neuropathic research mechanisms.
