Frequently Asked Questions

What is ARA-290?

ARA-290 is a synthetic 11-amino-acid peptide (sequence pyroGlu-Glu-Gln-Leu-Glu-Arg-Ala-Leu-Asn-Ser-Ser) derived from the helix-B domain of erythropoietin (EPO). It has CAS number 1208243-50-8, molecular formula C51H84N16O21, and a molecular weight of approximately 1257.3 g/mol. Pure Health Peptides supplies it as a lyophilized powder strictly for in vitro laboratory research.

Why is ARA-290 also called cibinetide?

Cibinetide is the international non-proprietary name for the same 11-residue erythropoietin-derived peptide; ARA-290 is the development code used across much of the research literature. The two names refer to an identical compound.

What is ARA-290 studied for in research?

In controlled laboratory settings, ARA-290 is studied as a peptide that engages the innate repair receptor - a heteroreceptor complex of the EPO receptor and the CD131 beta-common subunit. Research literature reports that it corresponds only to the helix-B surface region and is characterized as selective for this heteroreceptor complex rather than the homodimeric EPO receptor. These are research findings; all applications are non-clinical.

What are ARA-290's chemical specifications, and what size does it come in?

ARA-290 has the molecular formula C51H84N16O21 and a molecular weight of approximately 1257.3 g/mol (refer to the lot-specific Certificate of Analysis for the exact value). It is supplied as a lyophilized white powder in 10 mg and 20 mg vials at greater than or equal to 99% purity (HPLC). Store in a cool, dry place away from light and moisture, and consult the Safety Data Sheet before handling.

Where can I buy ARA-290, and is it third-party tested?

ARA-290 is available from Pure Health Peptides as research-grade material in 10 mg and 20 mg vials at greater than or equal to 99% HPLC-verified purity. Every production lot is third-party tested in the US, with a lot-specific Certificate of Analysis available for verification.

Is ARA-290 intended for human or clinical use?

No. ARA-290 is for research use only and is not intended for human or veterinary use. It has not been evaluated by the FDA and is not a drug, food, cosmetic, or dietary supplement. It is supplied only to qualified research professionals for in vitro laboratory research, and KYC verification is required prior to fulfillment. Any use outside of controlled in vitro research is strictly prohibited.
