ARA 290 — compound background
11-amino-acid EPO-derived linear peptide
ARA 290 (Cibinetide) is an 11-residue peptide modelled on the helix-B surface of erythropoietin. It was engineered to engage the innate repair receptor — a heteromer of the EPO receptor and the beta-common receptor — without the erythropoietic (red-blood-cell-stimulating) activity of full-length EPO.
Solubility & reconstitution
A short, hydrophilic linear peptide that dissolves readily in aqueous diluent without acidification. Solutions are clear and colourless.
Commonly worked at 1-5 mg/mL.
Storage
Sealed powder is stable at -20 °C long-term. Refrigerate at 2-8 °C and use promptly.
Commonly worked with for 2-4 weeks at 2-8 °C in bacteriostatic water.
Stability
No folded tertiary structure to lose — handling concerns are those of a small linear peptide, not a protein.
Reading the Certificate of Analysis
Confirm the observed mass matches the ~1257 Da target for the free peptide, and check whether peptide content is reported separately from chromatographic purity.
