Buy ARA-290 Peptide 16 mg Online

Buy ARA-290 Peptide 16 mg online from a trusted supplier of laboratory-grade research peptides designed for advanced scientific investigation. ARA-290, also known as Cibinetide, is a synthetic peptide derived from erythropoietin (EPO) that has gained attention in research focused on inflammation regulation, cellular protection, and tissue-repair mechanisms.

In experimental environments, peptides derived from erythropoietin are studied for their ability to activate protective signaling pathways without stimulating red blood cell production. ARA-290 is specifically engineered to selectively activate the innate repair receptor (IRR), which is associated with cytoprotective signaling, anti-inflammatory responses, and tissue regeneration processes.

Because of these properties, ARA-290 has become an important compound in research fields investigating neuroinflammation, metabolic signaling, neuropathic pathways, and cellular repair processes.

The ARA-290 Peptide 16 mg vial is produced using controlled peptide synthesis methods and packaged for professional laboratory environments. This compound is supplied strictly for research use only and is not intended for human consumption, medical treatment, veterinary use, or diagnostic purposes.

What Is ARA-290 Peptide?

ARA-290 is a synthetic peptide consisting of 11 amino acids derived from the helix-B region of erythropoietin (EPO). Unlike full-length erythropoietin, which stimulates red blood cell production, ARA-290 has been engineered to activate protective biological pathways without inducing erythropoiesis.

This selectivity makes ARA-290 a valuable tool for studying the tissue-protective signaling mechanisms associated with EPO while avoiding hematologic side effects.

In research models, ARA-290 interacts with the innate repair receptor (IRR)—a receptor complex formed by the erythropoietin receptor (EPOR) and the β-common receptor (CD131). Activation of this receptor triggers intracellular signaling pathways that regulate inflammation, cellular survival, and tissue repair.

Because this receptor is typically expressed during cellular stress or injury, researchers use ARA-290 to study how cells respond to inflammatory damage and tissue trauma.

Mechanism of Action in Research Models

The primary biological mechanism studied with ARA-290 involves its interaction with the innate repair receptor (IRR).

Innate Repair Receptor Activation

The innate repair receptor is activated primarily during tissue injury or inflammatory stress. When ARA-290 binds to this receptor complex, it triggers intracellular signaling cascades associated with cellular survival and tissue protection.

Key signaling pathways studied include:

• JAK2-STAT signaling

• PI3K-Akt survival pathways

• NF-κB inflammatory regulation

These pathways regulate processes such as apoptosis inhibition, inflammatory signaling, and cellular resilience.

Activation of these pathways can help reduce inflammatory responses and support tissue repair mechanisms in experimental models.

Anti-Inflammatory Cytokine Modulation

Research suggests that ARA-290 can influence inflammatory signaling by reducing the expression of certain pro-inflammatory cytokines such as TNF-α and IL-6.

Cytokines play an essential role in immune communication and inflammation regulation, making them important targets for studies involving inflammatory disorders and tissue injury.

Cellular Protection and Anti-Apoptotic Activity

Another key research area focuses on the peptide’s ability to influence anti-apoptotic signaling pathways, which help protect cells from programmed cell death during periods of stress or injury.

Experimental studies examining ischemia-reperfusion injury models have observed reduced cellular damage when these pathways are activated.
