ARA-290, also known as Cibinetide, is a synthetic 11-amino-acid helix B surface peptide derived from erythropoietin, studied in neuroprotection and tissue-protection research. It is supplied as a high-purity white lyophilized powder, >=99% by HPLC, in sealed vials for laboratory use. ARA-290 is investigated in research on tissue-protective signaling, neuroprotection, inflammation modulation and repair-related pathways, and is commonly applied in cell-based and preclinical studies. The lyophilized format provides good stability and reproducible reconstitution for consistent experimental dosing. Every batch is quality-controlled and batch-specific COA can be supplied on request. Unopened product should be kept sealed at 2-8 degree C away from light and moisture, with -20 degree C recommended for long-term storage. We accept both trial and bulk orders, and OEM and private-label service is available. This peptide is for laboratory research use only, not for human or veterinary purposes.
