Eleven-amino-acid peptide (cibinetide) derived from the helix-B surface of erythropoietin. Activates the innate repair receptor — the tissue-protective arm of EPO signalling — without the erythropoietic activity, so it does not raise haematocrit. Investigated in sarcoidosis-associated small-fibre neuropathy, where a Phase 2b trial measured small-nerve-fibre regeneration by corneal confocal microscopy. Holds orphan drug designation for that indication and has never been submitted for full approval. Supplied for in vitro research use only.

What you receive
A sealed vial of lyophilized ARA-290 at the size you select.
Tracked, insured shipping from Texas, dispatched within a day of payment.
Every batch is tested by an independent laboratory before it is
listed — purity by HPLC, identity by mass spectrometry.
Handling & storage
As supplied (lyophilized): stable at −20°C, protected from light and moisture. Short periods at room temperature during transit are normal for lyophilized material.
Once in solution: refrigerate at 2–8°C and protect from light. Solutions are far less stable than the dry powder.
Avoid repeated freeze–thaw cycles — aliquot instead if the material will be used across multiple sessions.
Reconstitution solvent depends on the compound; bacteriostatic water suits most, and IGF-class peptides need a low-pH solvent such as 0.6% acetic acid. Both are stocked under Lab Supplies.
Handling information describes the material as laboratory stock. It is not guidance for use in humans or animals.
