ARA-290 (Cibinetide) 10mg – Innate Repair Receptor Research Peptide

$80.00

ARA-290 (cibinetide) is an 11-amino-acid peptide modeled on helix B of erythropoietin. It is studied for selective activity at the innate repair receptor (EPOR/CD131) without the red-blood-cell effects of erythropoietin, in preclinical models of tissue protection, inflammation and small-fiber nerve signaling. 10mg lyophilized vial, third-party tested at 99.65% HPLC purity. Strictly for in-vitro laboratory research use only; not for human consumption.

Description

ARA-290 (Cibinetide) 10mg – Innate Repair Receptor Research Peptide

ARA-290, also known as cibinetide, is a synthetic 11-amino-acid peptide derived from the helix B surface of erythropoietin (EPO). Researchers use it to separate the tissue-protective signaling of EPO from its effect on red blood cell production: ARA-290 is studied as a selective ligand of the innate repair receptor, a complex of the EPO receptor and the beta common receptor (CD131).

Research Focus

  • Innate repair receptor signaling: used to study EPOR/CD131 activation independently of the classical EPO receptor homodimer.
  • Inflammation models: examined for effects on pro-inflammatory cytokine signaling and immune cell activity in preclinical work.
  • Nerve fiber research: studied in animal models of small-fiber neuropathy and neuropathic pain signaling.
  • Tissue protection: investigated in models of ischemic and metabolic tissue injury.
