ARA-290

ARA-290 (cibinetide; pHBSP) is an 11-residue synthetic research peptide modeled on the surface region of erythropoietin helix B. Published laboratory research examines ARA-290 in EPOR/CD131 receptor signaling and cellular-stress models. Its receptor profile makes it a research tool for studies of receptor selectivity and downstream pathway activity. This 10 mg research material is supplied as a white lyophilized powder. For lot RA102609-146W, Freedom Diagnostics confirmed ARA-290 identity by LC-MS and reported 99.46% purity by HPLC-UV. Both endotoxin replicates passed; the report lists assay sensitivity of ≤0.05 EU/mL. Batch documentation is available on this page. For research use only. Not for human or animal consumption. Not for diagnostic or therapeutic use.
