ARA-290 from Vial AU is a research peptide supplied in Australia (10mg) from Sydney, NSW, for in-vitro laboratory research only. It is not for human or veterinary use. Its certificate of analysis will be published in the certificate library once the current lot has been tested.
ARA-290 10mg – Research Grade Peptide ARA-290 10mg is a research peptide also known as cibinetide or pyroglutamate helix B surface peptide (pHBSP) . ARA-290 is an 11-amino-acid peptide engineered from the three-dimensional structure of the helix B region of erythropoietin (EPO). Unlike erythropoietin, ARA-290 was designed to investigate tissue-protective signalling without stimulating red blood cell production.

Keep the sealed vial dry, protected from light and frozen (around −20 °C) for long-term holding, and let it reach room temperature before opening to limit condensation. Solutions are far less stable than the lyophilised powder, so prepare them close to the experiment.
Supplied for laboratory use.Practice notes: storing lyophilised peptides, choosing a reconstitution solvent and peptide stability in solution. Use the concentration calculator for stock solutions in mg/mL and µM.
Ready-made sets that pair ARA-290 with the compounds it is most often studied alongside, at a bundle price.
