Overview
ARA-290 (cibinetide) is an 11-amino-acid peptide corresponding to the helix-B surface region of erythropoietin. It engages the innate repair receptor without the erythropoietic activity of the parent protein, which is precisely why it is used as a research tool.
Background
Structural work on erythropoietin showed that its tissue-protective signalling and its red-cell signalling run through different receptor complexes and different faces of the molecule. Isolating the helix-B face produced a peptide that separates the two.
Handling & storage
Reconstitute with our Laboratory Research Reconstitution Solution, running the diluent slowly down the inside wall of the vial rather than onto the powder cake, then swirl until clear — never shake. Store the sealed lyophilised vial at -20°C protected from light; once in solution, hold at 2-8°C and avoid repeated freeze-thaw cycling.
Documentation
Every strength is filled as its own lot and released only after identity is confirmed by mass spectrometry and purity quantified by reverse-phase HPLC. The certificate of analysis shipped with the vial matches the lot and batch printed on its label, and also reports endotoxin, sterility and heavy metals.

Lot release testing for this strength is in progress — the printed lot, batch and COA ID ship on the vial and post here as soon as the certificate is issued. No analytical values are published before the laboratory releases them.
Store sealed vials at -20°C away from light. Allow material to reach room temperature before opening to avoid condensation. Reconstitute slowly against the vial wall using an appropriate sterile diluent, then refrigerate.
