ARA-290 Research Overview
ARA-290 is a synthetic 11-amino-acid peptide derived from the helix-B domain of erythropoietin. Developed by Araim Pharmaceuticals (now Cibinetide), it activates the innate repair receptor (IRR) — a heteroreceptor of EPOR and CD131 — without binding the classical EPO receptor responsible for red-cell production.

Molecular formula C₅₆H₉₂N₁₆O₁₄, molecular weight 1,257.45 g/mol, sequence H-Gln-Glu-Gln-Leu-Glu-Arg-Ala-Leu-Asn-Ser-Ser-OH. ARA-290 selectively activates the tissue-protective innate repair receptor (IRR), triggering anti-inflammatory, anti-apoptotic and neuroprotective signaling without raising hemoglobin or hematocrit. Clinical trials in sarcoidosis-associated small-fiber neuropathy and diabetic neuropathy have shown reductions in pain scores and improvements in nerve fiber density. ARA-290 is supplied as lyophilized powder and is classified in our catalog under epo-derived peptide for epo-derived peptide work. Recorded research categories for this compound include neuropathic pain research, small-fiber neuropathy studies, diabetic neuropathy research, sarcoidosis-associated neuropathy studies. Handling notes: store at -20°c (freezer), protect the vial from light, and avoid repeated freeze–thaw cycles once reconstituted. Amino Fuel Labs publishes no dosing protocol for ARA-290: the compound is distributed for in-vitro and preclinical laboratory research only and is not intended for human or veterinary use.

Frequently Asked Questions
Why is ARA-290 used instead of EPO?
ARA-290 separates the tissue-protective effects of EPO (via the IRR) from its erythropoietic effects (via the EPOR homodimer). Researchers get the neuroprotection without raising hematocrit.
What's the strongest published evidence for ARA-290?
Phase II trials in sarcoidosis-associated small-fiber neuropathy showed significant reduction in neuropathic pain scores and improvements in intra-epidermal nerve fiber density.
Do you provide a COA?
Yes. ≥99.2% HPLC purity, mass-spec confirmation, endotoxin testing — included on every batch.
What is ARA-290 studied for?
ARA-290 appears in laboratory research covering neuropathy treatment, diabetic complications, wound healing. All references describe in-vitro and preclinical study models only.
Does ARA-290 include a Certificate of Analysis?
Yes. Each ARA-290 lot ships with a batch-specific third-party Certificate of Analysis reporting 99.2% purity by reversed-phase HPLC alongside mass-spectrometry identity confirmation.
What form does ARA-290 arrive in?
ARA-290 is supplied as lyophilized powder in a sealed vial, packed with the lot documentation for the exact batch shipped.
