ARA-290 Nasal Spray

Product Overview

ARA-290 Nasal Spray is a synthetic, nonerythropoietic peptide available from Direct Anti Peptide for qualified research professionals and licensed laboratory environments. Formulated at ≥98% purity, this compound is designed to activate the innate repair receptor (IRR), a heteromeric complex distinct from the classical erythropoietin receptor signaling pathway responsible for red blood cell production. By selectively engaging the IRR, ARA-290 has become a subject of significant scientific interest across multiple preclinical research domains, including neuropathic pain modeling, inflammatory pathway analysis, and tissue repair biology. Researchers seeking to buy ARA-290 online will find this product competitively priced and backed by rigorous quality standards at Direct Anti Peptide.

Peptide Structure & Amino Acid Sequence

ARA-290 is an 11-amino acid cyclic peptide derived from the helix B surface peptide (HBSP) region of erythropoietin. Its engineered structure preserves the tissue-protective signaling properties of the parent molecule while eliminating erythropoietic activity. The cyclic configuration enhances conformational stability, allowing the peptide to engage the innate repair receptor with high specificity. This structural design is central to its utility in research models examining neuroprotection, immune modulation, and cellular repair without confounding hematopoietic variables.

Chemical & Physical Characteristics

• Type: Synthetic cyclic peptide
• Target Receptor: Innate Repair Receptor (IRR) / EPO receptor heteromer
• Erythropoietic Activity: None — nonerythropoietic by design
• Formulation: Nasal spray liquid format
• Purity: ≥98% (HPLC-verified)
• Appearance: Clear to slightly opalescent aqueous solution
• Storage Compatibility: Refrigerated conditions; protect from light and repeated freeze-thaw cycles

The nasal spray delivery format is intended solely for research administration models and laboratory investigational use. It is not formulated or approved for human therapeutic application.

Purity & Analytical Verification (HPLC & MS)

Every batch of ARA-290 Nasal Spray supplied by Direct Anti Peptide undergoes stringent analytical testing prior to release. High-performance liquid chromatography (HPLC) is employed to confirm peptide purity at ≥98%, while mass spectrometry (MS) validates the molecular identity and integrity of the compound. These dual verification methods ensure that researchers receive a consistent, reliable product suitable for reproducible experimental outcomes. Certificate of Analysis (CoA) documentation is available upon request, providing full traceability for each lot.

Quality Control & Lyophilization Integrity

While ARA-290 Nasal Spray is supplied in liquid format rather than lyophilized powder, the same commitment to quality control standards applies. The formulation process adheres to established protocols for peptide stability in aqueous solution, including pH optimization and excipient selection appropriate for research-grade nasal spray preparations. Batch-to-batch consistency is maintained through standardized manufacturing controls, ensuring that each unit ordered from Direct Anti Peptide meets the declared specification.

Safety, Handling & Laboratory Precautions

ARA-290 Nasal Spray is a research-grade compound and must be handled exclusively by trained scientific professionals in appropriately equipped laboratory settings. Standard laboratory personal protective equipment (PPE), including gloves, eye protection, and lab coat, should be worn at all times during handling. The compound should be kept away from unauthorized personnel, and all waste disposal must comply with applicable institutional and regulatory guidelines. This product is not a consumer product and carries no safety assessment for human exposure.

Reconstitution, Packaging & Storage

ARA-290 Nasal Spray is supplied ready-to-use in nasal spray format. No reconstitution is required. Store at 2–8°C in a refrigerated environment, protected from direct light and temperature fluctuations. Do not freeze unless specified by your institutional protocol. Packaging is designed to maintain product integrity during transit and short-term laboratory storage. Researchers are advised to review the accompanying CoA and storage guidelines upon receipt to ensure optimal compound stability throughout the research period.
