About ARA-290
ARA-290 (cibinetide; pHBSP) is an 11-residue synthetic research peptide modeled on the surface region of erythropoietin helix B.
Published laboratory research examines ARA-290 in EPOR/CD131 receptor signaling and cellular-stress models. Its receptor profile makes it a research tool for studies of receptor selectivity and downstream pathway activity.
This 10 mg research material is supplied as a white lyophilized powder. For lot RA102609-146W, Freedom Diagnostics confirmed ARA-290 identity by LC-MS and reported 99.46% purity by HPLC-UV. Both endotoxin replicates passed; the report lists assay sensitivity of ≤0.05 EU/mL. Batch documentation is available on this page.
For research use only. Not for human or animal consumption. Not for diagnostic or therapeutic use.

You ask,
we answer.
Are these peptides quality tested?
Absolutely. Our analytical testing is conducted by Janoshik Analytical, BioRegen, or Freedom Diagnostics, independent third-party laboratories that verify the identity, purity, and composition of our research products. All products are guaranteed to test at 98% purity or higher. Each CoA includes purity analysis, peptide sequence confirmation, date of analysis, and an endotoxin report.
What are typical delivery times?
Free 2-Day Air shipping is available when qualifying merchandise totals reach $200. Overnight Air is also available. Please allow up to 24 hours for processing.
Every package comes with professional packaging and tracking updates via email.
How should these compounds be stored?
Our peptides are shipped in lyophilized form, which is stable at room temperature during transit. Once received, store unopened vials in a cool, dry place.
Are products stable during shipping?
Our peptides are shipped in lyophilized (freeze-dried) form, which ensures stability during transit. This powder form is highly stable at room temperature and resistant to temperature fluctuations that occur during shipping.
Research has shown no significant degradation or loss of purity when lyophilized peptides are exposed to room temperature during typical shipping timeframes. Each batch is verified for purity upon production, and our stability testing confirms maintenance of product integrity during standard shipping conditions.
What are your bulk ordering options?
For bulk inquiries and volume pricing, please contact us.
What is the shelf life/expiration of unopened vials?
Each lot lists a best-by/expiration on the vial label and COA. As general guidance, lyophilized peptides stored as directed are typically stable 12–24 months (often longer at –20 °C). Short shipping periods at ambient temperature are normal. Actual stability depends on sequence and storage conditions.
