What is ARA-290?
ARA-290, also called cibinetide, is an 11-amino-acid peptide derived from the helix B domain of erythropoietin. It binds the innate repair receptor without the haematopoietic activity of the parent hormone, which is the point of the fragment: tissue-protective signalling can be studied without the erythropoietic confound. Pepstral supplies it as a lyophilized powder for in-vitro laboratory research only.

What is ARA-290 studied for?
- Innate repair receptor binding assays
- Neuropathy and small-fibre models
- Tissue-protection studies
- Erythropoietin fragment comparisons
All applications above are in-vitro or preclinical research contexts. ARA-290 is sold for laboratory research only and is not for human or animal use.
What does the certificate for lot ARA2901-0803 show?
Every lot of ARA-290 is tested by an independent US laboratory before it is listed. The report for lot ARA2901-0803 is in the COA library and the lot number printed on the vial matches it. The current results:
| Test | Method | Lot ARA2901-0803 result |
|---|---|---|
| Identity | LC-MS/MS | ARA-290 · conforms |
| Content | HPLC quantitation | 10.86 mg |
| Purity | RP-HPLC (214 nm) | 99.72% |
| Endotoxin | USP <85> | <0.05 EU/mL |
| Heavy metals | USP <232> | <0.01 ppm |
How is ARA-290 handled and stored?
Sealed vials are stored at -20°C away from light and keep for 24 months. To reconstitute, add bacteriostatic water slowly down the inside wall of the vial and swirl until clear; never shake. Once in solution, keep at 2 to 8°C and use within our 28-day default for a preserved solution. The concentration table gives the dilution volumes and microlitre aliquots for this vial.
Frequently asked questions
Does ARA-290 raise red cell counts?
No. It was designed to engage the innate repair receptor without the erythropoietin receptor activity that drives haematopoiesis, which is why it is used where that confound matters.
What is the innate repair receptor?
A heteromer of the erythropoietin receptor and the beta-common receptor, distinct from the homodimeric receptor that drives red cell production.
Is ARA-290 for human use?
No. Every product on this site is sold for in-vitro laboratory research only and is not for human or animal consumption, diagnostic or therapeutic use.
