ARA 290
EPO-derived peptide studied for anti-inflammatory activity, nerve repair, and neuropathic-pain research.
Molecular reference
Research background
ARA 290 — also known as Cibinetide — is the peptide researchers turn to when the subject is nerve comfort, stubborn inflammation, and tissue repair. It is an 11-amino-acid fragment modelled on erythropoietin (EPO), engineered to switch on the body's innate repair receptor without EPO's effect on red-blood-cell production. Published work has studied it around neuropathic pain, anti-inflammatory signalling, and healing in preclinical models.
Because it targets repair signalling rather than blood-cell production, ARA 290 is studied as a cleaner tool for inflammation and nerve-related research questions.

Reconstitution
- Supplied as a lyophilized (freeze-dried) powder for laboratory reconstitution.
- Bacteriostatic water (0.9% benzyl alcohol) is the most common reconstitution solvent for multi-use research handling; sterile or acetic-acid solutions are used for specific compounds.
- Introduce solvent slowly against the vial wall rather than directly onto the powder, and allow it to dissolve without vigorous shaking.
- Use the reconstitution calculator to determine solvent volume for a target concentration in your protocol.
Storage & handling
- Lyophilized powder: store sealed at -20 °C for long-term stability; short periods at 2–8 °C are generally acceptable.
- Once reconstituted: refrigerate at 2–8 °C and protect from light; use within the compound-specific window noted on the COA.
- Avoid repeated freeze–thaw cycles of reconstituted solution.
- Keep away from direct light and heat at all times.
Purity & verification
Every Popular Peptides batch is third-party tested by HPLC and LC-MS with a published Certificate of Analysis (≥99% purity).
