ARA-290 16 mg: research material

Buy Ara-290 16 mg for laboratory research, supplied as lyophilized powder in one boxed 3 mL vial.

ARA-290 is an 11-amino-acid research peptide designed around structural features of erythropoietin (EPO). Research publications also use the names cibinetide and pyroglutamate helix B surface peptide (pHBSP).

Published ARA-290 / cibinetide terminology

Choose the material and presentation

ARA-290 is distinct from the much larger EPO protein. Its design reflects residues exposed on EPO’s three-dimensional surface, rather than simply reproducing an uninterrupted stretch of the protein sequence.

When matching a method, check the construct and terminal modification as well as the name. A published synonym helps locate research; it does not by itself verify the identity or analytical results of an individual lot.

How the EPO-derived peptide was studied

Brines and colleagues compared short EPO-related peptides in experimental injury models. The 11-residue surface design and its pyroglutamate form were studied separately from the full helix-B peptide. The work included renal ischemia-reperfusion measurements and tests of red-blood-cell production, or erythropoiesis.

The reported tissue responses were not accompanied by erythropoiesis in those experiments. This was a feature of the tested constructs and conditions, not evidence that all EPO-related peptides are interchangeable or that this product treats a human disease.

Product records and batch reports

The product documentation section provides available product files and lot-specific reports. Use those records for the supplied material’s identity and measured results. Literature about an EPO-derived peptide cannot substitute for a batch report, and a purity result alone does not confirm the terminal modification.
