What ARA-290 is

ARA-290, also known by its drug name cibinetide, started out as erythropoietin, the hormone that tells bone marrow to make red blood cells, before researchers filed it down to a much smaller piece. They reshaped one segment, called helix B, so it would no longer raise red blood cell counts but would still switch on a separate, smaller receptor involved in tissue repair. Think of erythropoietin as a master key that opens several locks, and ARA-290 as a copy ground down to open just one.

ARA-290 is a laboratory reference material. SBz Industries sells it for laboratory research.

Available sizes: 10 mg

Research

What the research has looked at

In plain terms, with a link to every study. The most useful thing to notice is what each study was done in.

ARA-290 is unusual on this site because real human trial data exists, not just animal work. It has been tested in small, placebo-controlled human studies in adults with nerve damage linked to other long-term conditions, alongside earlier lab and animal work summarized in review articles.

review2015

This review pulled together lab, animal, and human clinical trial data on ARA-290, tracing how a peptide that clears the bloodstream within a couple of minutes can still trigger repair effects that last for days by switching on a specific receptor pairing found mainly at sites of injury or stress.

Flipping the molecular switch for innate protection and repair of tissues: Long-lasting effects of a non-erythropoietic small peptide engineered from erythropoietin.
Collino and colleagues, Pharmacology & Therapeutics

people2013

A blinded, placebo-controlled trial in adults with damage to the small nerve fibers in their skin and eyes. For about a month they got ARA-290 or a placebo, and the team measured nerve fiber density on the surface of the eye and how far people walked in six minutes.

ARA 290 improves symptoms in patients with sarcoidosis-associated small nerve fiber loss and increases corneal nerve fiber density.
Dahan and colleagues, Molecular Medicine

people2015

Adults with long-term nerve symptoms and hard-to-control blood sugar got ARA-290 or a placebo for about a month and were followed for another month. The team tracked blood sugar readings, cholesterol, a standard nerve-symptom questionnaire and nerve fiber density in the eye.

ARA 290, a nonerythropoietic peptide engineered from erythropoietin, improves metabolic control and neuropathic symptoms in patients with type 2 diabetes.

Handling

Mixing and storage

Full handling guide

01
Let it warm up
Give the vial twenty minutes on the bench before opening it, so water does not condense onto the powder.
02
Add bacteriostatic water
Slowly, down the inside wall of the vial, never straight onto the powder.
03
Let it dissolve
Leave it alone until it clears. Do not shake it. Shaking damages the peptide.
04
Refrigerate and use
Once mixed, it breaks down much faster than the dry powder. Keep it cold and dark.

Questions

Common questions about ARA-290

What is ARA-290?

ARA-290, also known by its drug name cibinetide, started out as erythropoietin, the hormone that tells bone marrow to make red blood cells, before researchers filed it down to a much smaller piece. They reshaped one segment, called helix B, so it would no longer raise red blood cell counts but would still switch on a separate, smaller receptor involved in tissue repair. Think of erythropoietin as a master key that opens several locks, and ARA-290 as a copy ground down to open just one. SBz Industries sells it for laboratory research only.

Has ARA-290 actually been tested in people, not just animals?

Yes. Unlike most compounds here, it has gone through small, blinded, placebo-controlled human trials in adults with nerve damage linked to other long-term conditions. The groups were small and the work comes from a few teams.

Why is ARA-290 also called cibinetide?

Cibinetide is the generic drug name assigned to the same molecule once it entered formal drug development. ARA-290 is the earlier research code name from the same manufacturer.

How is ARA-290 reconstituted?

ARA-290 ships as a freeze-dried powder. Mix it with bacteriostatic water, added slowly down the inside wall of the vial, and let it dissolve without shaking. The researcher decides the working concentration, not us, and we publish no protocols.

How should ARA-290 be stored?

Store as stated on the product page and the certificate of analysis. Vials ship in plain outer packaging with no product name on the outside.

Is ARA-290 tested, and can I see the results?

Yes. An independent lab tests every compound: it confirms the compound is what the label says and measures purity by HPLC. The latest certificate is on the product page, and you can read it before you order.

Who is permitted to purchase ARA-290?

Researchers and institutions, 21 or over. By ordering you confirm the material is for laboratory research and will not be used in humans or animals.
