ARA-290 Spray
ARA-290 Spray supplies the 11-residue erythropoietin-derived peptide as a pre-dissolved metered solution, engineered to engage the innate repair receptor without activating the receptor that drives red cell production. Every wholesale lot is ≥99.0% HPLC and LC-MS verified with a batch-specific certificate of analysis. Supplied for Research Use Only (RUO) — not for human consumption or therapeutic use. This liquid compound is synthesized and purified for the sole purpose of scientific investigation. This material is supplied strictly for laboratory research purposes and in-vitro scientific testing in controlled developmental or academic settings. It is not designed, approved, or intended under any circumstances for human consumption, clinical application, medical diagnostics, or direct therapeutic administration.

Clinical Dossier & Technical Digest
Factual reference profile and clinical data specifications.
Tissue protection groups and receptor biology labs are the primary users of ARA-290, and the defining experiment is a negative control as much as a positive one. A lab studying the innate repair receptor will treat cells expressing both the erythropoietin receptor and the beta-common subunit and measure protective signaling, then run the same treatment on cells expressing only the homodimeric erythropoietin receptor and confirm no response. That pairing is what demonstrates the design worked. Brines and colleagues built this framework in 2008 with nonerythropoietic tissue-protective peptides derived from erythropoietin tertiary structure. Applied work has followed into islet and retinal models, where Yao and colleagues reported improved islet allograft function using the same innate repair receptor ligand.
ARA-290 is analytically among the more straightforward compounds in the catalog, and its structure explains why. At 11 residues and roughly 1257 Da it produces a clean, well-resolved reverse-phase peak and a single-charge mass confirmation without the multiply-charged envelope larger peptides require. It carries no cysteine, so disulfide scrambling is not part of the panel, and no methionine, so oxidation is not the dominant degradation route it is for many short peptides. What is monitored instead is truncated chains from incomplete coupling and deamidation at the amide-bearing residues. One point deserves emphasis in the identity check: because the sequence reproduces a structural surface of a folded protein rather than a contiguous fragment, position-by-position sequence confirmation matters more than usual.

Analytical Quality Assurance Loop
Every lot of ARA-290 Spray undergoes a double-pass chromatography and verification process. We confirm purity by reverse-phase HPLC and identity by exact cation mass using Liquid Chromatography-Mass Spectrometry (LC-MS), alongside metered-solution concentration verification. Finished units are sterile-filtered, nitrogen-purged, and filled into amber glass for long-term molecular stability.

ARA-290 Spray Procurement FAQ
Complete institutional procurement guidance, quality verification protocols, and delivery details for bulk wholesale ARA-290 Spray.
What is the verified purity and analytical testing protocol for wholesale ARA-290 Spray?
Every wholesale lot of ARA-290 Spray is verified to ≥99.0% purity by reverse-phase HPLC and confirmed by LC-MS against the expected mass near 1257 Da. Each shipment carries a batch-specific certificate of analysis. Truncated sequences are the main synthesis-related screen for an 11-residue chain, alongside deamidation at the asparagine and glutamine positions. Because the peptide reproduces a structural surface rather than a linear fragment, sequence fidelity is confirmed position by position.
02Is ARA-290 Spray approved for therapeutic use or human consumption?
+
Is ARA-290 Spray approved for therapeutic use or human consumption?
No. ARA-290 Spray is supplied strictly as a Research Use Only (RUO) material for in-vitro laboratory investigation. It is not approved, indicated, or intended for human consumption, medical treatment, diagnostic procedures, veterinary application, or cosmetic use. This RUO material is not a pharmaceutical product and carries no approved indication.
03What is the minimum order quantity for wholesale ARA-290 Spray?
+
What is the minimum order quantity for wholesale ARA-290 Spray?
The minimum order quantity is 10 spray units, which constitutes one standard wholesale kit. 99 Purity Wholesale supplies bulk quantities to research institutions, contract laboratories running tissue protection and receptor heterocomplex panels, and distribution brands. We do not fulfill retail or single-unit inquiries.
04What physical form is wholesale ARA-290 Spray supplied in?
+
What physical form is wholesale ARA-290 Spray supplied in?
ARA-290 Spray is supplied as a pre-dissolved, sterile-filtered solution in amber glass bottles fitted with a metered atomizer, at 10 mg per unit. At 11 residues it dissolves readily in aqueous buffer without an organic co-solvent, and it carries no cysteine so there is no disulfide to protect. Headspace is nitrogen-purged before capping, and no reconstitution step is required.
05What are the recommended storage conditions and stability limits for ARA-290 Spray?
+
What are the recommended storage conditions and stability limits for ARA-290 Spray?
Store ARA-290 Spray refrigerated at 2°C to 8°C (36°F to 46°F), upright and protected from light, where sealed units remain within specification for up to 24 months. Once the atomizer is first actuated, use the unit within 30 days. Short peptides tolerate handling better than long chains and this one carries no disulfide bond to scramble, but avoid freeze-thaw cycling because it accelerates deamidation at the amide-bearing residues. Brief transit excursions to 15°C to 25°C (59°F to 77°F) are tolerated.
06What is the primary molecular target or mechanism of action researched for ARA-290 Spray?
+
What is the primary molecular target or mechanism of action researched for ARA-290 Spray?
ARA-290 is an 11-residue peptide with an unusual origin: rather than being cut from the linear sequence of erythropoietin, it reproduces a structural surface, the outward-facing residues of one helical face of the folded protein. That design choice is the whole point. Research shows it engages the innate repair receptor, a heterocomplex formed when the erythropoietin receptor pairs with the beta-common receptor subunit, while deliberately avoiding the homodimeric erythropoietin receptor that drives red blood cell production. Brines and colleagues established this separation in 2008, showing that tissue-protective signaling and erythropoiesis run through structurally distinct receptor assemblies. The compound therefore engages a repair pathway without the haematological consequence that limits erythropoietin itself.
07Can I request custom concentrations, vial sizes, or formulations for wholesale ARA-290 Spray?

How is wholesale ARA-290 Spray packaged and shipped to preserve compound integrity?
Units ship in light-blocking, vacuum-sealed secondary packaging with temperature-stability buffers that hold the shipment inside the refrigerated range through transit. Amber primary containers and nitrogen-purged headspace protect the short chain against adsorption and the aromatic residues from light. We ship nationwide across all 50 US states and internationally via express couriers with discrete, border-optimized clearance and full delivery assurance.
