Certificate Reference
For continuity with the current catalog, this page links to laboratory documentation for a component or a closely related product. The linked certificate is a reference only and is not represented as the batch-specific COA for ARA-290.
Overview
ARA-290, also known as cibinetide or pHBSP, is an 11-amino-acid peptide engineered from the tissue-protective region of erythropoietin. It was designed to engage the innate repair receptor without stimulating red-blood-cell production, creating a focused model for inflammation, tissue repair, and nerve-injury signaling.

Research Focus
WHAT THIS FORMULA FEATURES
Selective activation of the EPOR/CD131 innate repair receptor is the central research feature. Published work has examined neuropathic signaling, corneal nerve-fiber density, endothelial progenitor-cell migration, inflammatory responses, and tissue-protective pathways.
EXPECTED RESEARCH READOUTS
Typical endpoints include inflammatory cytokines, nerve-fiber density, sensory or allodynia measures in animal models, endothelial-cell proliferation/migration, oxidative-stress resistance, and repair-pathway signaling. Effects are highly model- and injury-context dependent.
Research endpoints described above reflect published or model-based scientific observations and are not guaranteed outcomes. This product is strictly for research purposes only. Not approved for human or animal use.
