ARA-290 is an 11-amino-acid peptide derived from the beta domain of the erythropoietin protein. This peptide fragment has been investigated in research models for its involvement in cellular protection and structural maintenance pathways.

Preclinical investigations have suggested that ARA-290 may influence endothelial colony-forming cells (ECFCs) within controlled laboratory models. It has also been studied for its interactions with innate cellular defense pathways and microbial-associated signaling mechanisms in experimental research conditions.

How Does ARA-290 Peptide Work?

ARA-290 is an 11-amino-acid peptide fragment that is derived from the β-helix region of erythropoietin. It is being investigated in experimental systems for its interaction with the innate repair receptor (IRR). The IRR is a heteromeric receptor complex composed of the erythropoietin receptor and the β-common receptor.

Binding to this receptor complex is proposed to initiate intracellular signaling cascades in research preclinical models. This includes pathways associated with JAK2-mediated signal transduction, which may influence inflammatory signaling modulation and maintenance of cellular integrity.

Research Findings on ARA-290

ARA-290 and Neuropathic Pain Modulation

Experimental research investigating ARA-290 in nerve-injury models reported that the peptide reduced mechanical and cold allodynia in models. The study also showed that ARA-290 suppressed activation of spinal microglia, which are immune cells involved in neuroinflammation and chronic pain signaling.

ARA-290 and Oxidative Stress Protection in Cellular Models

Cell-based research examining ARA-290 found that the peptide reduced oxidative stress and DNA damage caused by doxorubicin exposure. The study suggested that ARA-290 may activate protective cellular pathways linked to the erythropoietin-derived innate repair receptor without stimulating erythropoiesis. These results highlight the peptide’s potential role in cytoprotective mechanisms during experimental investigations.

Frequently Asked Questions

What is ARA-290?

ARA-290 (Cibinetide) is a synthetic peptide derived from a region of the erythropoietin molecule and studied as a reference compound in laboratory research. PureRawz Australia supplies it for in vitro and non-clinical investigation only.

Is ARA-290 legal or approved in Australia?

ARA-290 is not an approved therapeutic good and is not registered on the Australian Register of Therapeutic Goods for any use. It is provided for laboratory research use only, with the researcher responsible for meeting TGA and Australian regulatory obligations.

How is ARA-290 tested?

Each batch is characterised by third-party laboratories using HPLC and mass spectrometry to confirm identity and purity. A batch certificate of analysis (COA) reflecting purity of at least 99% is available for reference.

How should ARA-290 be stored for research use?

Lyophilised ARA-290 is generally stored frozen and kept away from light and moisture to support long-term stability. Once reconstituted, it is typically held refrigerated and used within a short period per the researcher's handling protocols.
