ARA-290 (cibinetide) is an 11-amino-acid synthetic peptide derived from the erythropoietin (EPO) sequence. It is used in laboratory research as a selective ligand for the innate repair receptor (IRR), a heteromeric receptor complex composed of the erythropoietin receptor and the β-common receptor. It is supplied strictly for laboratory research use only and is not approved or intended for human or animal use, ingestion, dosing, or therapeutic application. Published research context In the peer-reviewed literature the IRR is described as being expressed at low levels under baseline conditions and upregulated in experimental models of tissue stress, inflammation, or ischemia. Published in-vitro and animal-model studies have characterised IRR activation in relation to: • Inflammatory signalling cascades • Cytokine expression profiles • Apoptotic and oxidative-stress markers • Tissue-remodelling and regeneration models • Neuronal-signalling models Published work also reports that cibinetide does not substantially activate the homodimeric erythropoietin receptor associated with erythropoiesis, which is why it is frequently used as a comparator to EPO in receptor-selectivity experiments. These descriptions summarise published experimental observations only and are provided for scientific context. They must not be interpreted as claims of therapeutic, diagnostic, or clinical benefit.

SS-31 is a laboratory research peptide used to study mitochondrial membrane interactions, cardiolipin binding, and cellular signaling pathways in controlled experimental systems. This product is supplied strictly for research use only. It is not approved or intended for human or animal use, and any discussion of biological activity refers only to preclinical or in vitro research. One of the unique aspects of SS-31 is its specific affinity for cardiolipin, a phospholipid located within the inner mitochondrial membrane that is essential for maintaining electron transport chain structure and membrane integrity. Disturbances in cardiolipin stability are commonly examined in research involving oxidative stress, mitochondrial dysfunction, and bioenergetic decline. SS-31’s ability to interact with cardiolipin has therefore made it a recurring subject in studies investigating how mitochondrial membrane condition affects broader cellular behavior. Additionally, research has documented that SS-31 may influence the production of reactive oxygen species (ROS) at the mitochondrial level. Excessive ROS production is commonly evaluated in studies on cellular stress, inflammation, and mitochondrial impairment. By focusing on mitochondria directly, rather than acting as a broad-spectrum antioxidant, SS-31 offers researchers a pathway to study targeted mechanisms of oxidative modulation rather than systemic antioxidant activity. For laboratory use, SS-31 is commonly supplied as a high-purity, LPS-free peptide, manufactured to meet strict research standards. As an endotoxin-free peptide, it is frequently utilized in sensitive in vitro and ex vivo experimental setups where contamination control is critical. Research peptides such as SS-31 are typically endotoxin tested to support reproducibility and reliability across mitochondrial and cellular research applications. This compound is intended strictly for research use only and is not approved for human or animal use. -
