ARA-290 at a glance

Erythropoietin has two jobs: driving red blood cell production and, separately, protecting stressed tissue. ARA-290, given the nonproprietary name cibinetide, was designed by Araim Pharmaceuticals to capture the second role alone. Its 11 residues mimic the three-dimensional surface of EPO's helix B, a face that does not take part in hematopoietic receptor binding. Its reported molecular weight is around 1257 g/mol, and research material is supplied as a lyophilized powder.

Price and availability

This is Lab77 Peptides‘s single 10mg vial, dispatched from the United States. $50.00 buys the whole kit, which is $5.00/mg. 4 brands sell ARA-290 on GLP1 Forum Escrow, with a typical price of $0.656–$0.85 per mg (median $0.85); this listing is above the typical range. Funds stay in escrow and are released to Lab77 Peptides only when you mark the order as received.

What it is studied for

Hematopoietic signaling requires a homodimer of the EPO receptor. Tissue-protective signaling is attributed instead to a heteromeric complex in which the EPO receptor partners with the beta-common receptor, CD131, a combination called the innate repair receptor. This receptor is reported to be upregulated in injured or inflamed tissue. Engagement by cibinetide has been associated in animal models with reduced pro-inflammatory cytokine signaling, preservation of small nerve fibers and improved metabolic markers. The innate repair receptor model itself is still debated, and some researchers question whether CD131 is required in every tissue.

Research and regulatory status

Cibinetide has reached human trials, which sets it apart from most catalogue peptides. Small randomized studies in sarcoidosis-related small-fiber neuropathy and in diabetic neuropathy reported changes in corneal nerve fiber measures and symptom scores. No regulator has approved it, and larger confirmatory trials have not been published. Preclinical work continues in inflammation, retinopathy and metabolic-disease models, so it is best described as an investigational compound with early human data.

Checking the lab data

Mass spectrometry should return a mass close to the roughly 1257 g/mol cited for cibinetide, confirming the full sequence rather than a truncated or substituted peptide. Since catalogues sometimes print incomplete sequence strings, the report's sequence line deserves a careful read against the published structure. HPLC purity, the batch number and the test date from an independent lab complete the picture. The vial should contain a white lyophilized cake.

Synonyms: Cibinetide
Class: EPO-derived innate repair receptor agonist (11-amino-acid peptide)
Format: Lyophilized (freeze-dried) powder
Vial strength: 10mg
Total content: 10 mg
Price per mg: $5.00
Sold by: Lab77 Peptides

Storage and preparation

Keep unopened freeze-dried vials cold, sealed and out of the light; moisture is what degrades a lyophilized cake fastest. After reconstitution, refrigerate the solution and work within the stability window your protocol sets.

Concentration arithmetic: one 10 mg vial dissolved in 2 mL gives 5 mg/mL, or 10 mg/mL in 1 mL. The Research Lab calculator in your dashboard handles any other volume.

Buyer questions

Why is ARA-290 described as acting where tissue is already injured?

Researchers report that the innate repair receptor is expressed at low levels in healthy tissue and increases in response to injury, inflammation or metabolic stress. That pattern is proposed to explain why cibinetide's effects in animal models appear mostly in damaged tissue, though the receptor's regulation in humans is not fully characterized.

Is cibinetide the same as ARA-290?

Yes. ARA-290 is the developer's research code, and cibinetide is the international nonproprietary name assigned later. Clinical trial registries and journal articles use both, so searching each term gives a fuller view. Older papers may describe the same design as a pyroglutamate helix B surface peptide, abbreviated pHBSP.
