ARA-290 10mg

ARA-290 10mg is a synthetic research peptide intended exclusively for laboratory, analytical, and scientific investigation.

Also known as Cibinetide, pHBSP, and pyroglutamate helix-B surface peptide, ARA-290 is an 11-amino-acid peptide engineered from the three-dimensional helix-B region of erythropoietin. Research literature characterizes it as a selective ligand of the innate repair receptor (IRR), a heteromeric receptor involving the erythropoietin receptor and the β-common receptor CD131.

FDA’s substance database recognizes ARA-290 and Cibinetide as synonyms and identifies the peptide under UNII 9W5677JKDA. FDA specifically notes that assignment of a UNII does not imply regulatory review or approval.

Research Applications

ARA-290 may be of interest in controlled experimental work involving:

• Innate repair receptor signaling
• EPOR/CD131 receptor interactions
• Neuropeptide research
• Cellular signaling pathways
• Inflammatory signaling models
• Peptide–receptor interaction studies
• Structure–activity relationships
• Peptide stability research
• Molecular characterization
• Analytical method development
• In-vitro and preclinical research models

Published studies have investigated ARA-290 in cellular, animal, and limited clinical research involving IRR signaling and neurological pathways. Those findings should not be interpreted as establishing that a research-grade ARA-290 product is safe, effective, or approved for human treatment.

Why Researchers Choose ARA-290

ARA-290 offers researchers a well-characterized 11-residue peptide structure with a defined receptor-associated research pathway.

Its documented identity as Cibinetide/ARA-290 makes it useful for experimental programs focused on receptor biology, cellular signaling, peptide characterization, and comparative molecular research.

Research Use Only

ARA-290 10mg from Peptides R US is intended exclusively for laboratory, analytical, and scientific research.

It is not intended for human or veterinary consumption or administration and is not intended to diagnose, treat, cure, mitigate, or prevent any disease or medical condition.

No injection, dosage, reconstitution-for-human-use, pain-management, therapeutic, or clinical instructions are provided or implied.

FDA’s 503A bulk-substance materials have listed Cibinetide (ARA-290) among substances nominated without adequate support for compounding under that pathway. This should not be confused with FDA approval of an ARA-290 product.
