Contents Cibinetide Form / storage Lyophilized powder; store at −20 °C, protect from light Purity ≥98% — see lot COA CAS 1208243-50-8 Molecular formula C51H84N16O21 Molecular weight 1257.3 g/mol Testing Identity (UV/Vis λmax), purity, assay (Beer-Lambert), heavy metals, microbial (TAMC/TYMC) COA Batch-specific — view on this page Research background ARA-290 is an 11-residue peptide engineered from the aqueous-facing surface of EPO’s helix B, designed to selectively engage the proposed innate repair receptor (IRR) rather than the classical erythropoietin receptor — so tissue-protective signaling can be studied independently of red-blood-cell stimulation. Its N-terminal pyroglutamate contributes structural stability. Research has examined it in models of neuropathic and inflammatory conditions, with attention to proposed cytoprotective and anti-inflammatory signaling. Research applications Preclinical neuropathy / small-fiber models Innate-repair-receptor and anti-inflammatory signaling studies Research analog for tissue-protective EPO pathways without erythropoiesis Quality & documentation Every lot is tested by an independent third-party laboratory before it enters the catalog.
