Core Molecular Specs & Technical Index
ARA 290 peptide is a synthetic, linear peptide consisting of 11 amino acids. It is derived from the natural sequence of erythropoietin (EPO) but is engineered to be non-erythropoietic, meaning it does not stimulate red blood cell production. This makes it a highly specific tool for researchers and formulators targeting non-hematopoietic pathways. The core buyer group includes cosmetic ingredient suppliers, laboratory research institutions, and bulk peptide distributors seeking a high-purity, stable raw material for advanced formulations.
The molecular formula of ARA 290 is C55H85N15O16, with a molecular weight of approximately 1188.36 g/mol. It is supplied as a white lyophilized powder, ensuring maximum stability during transport and storage. The peptide sequence is H-Arg-Glu-Gln-Glu-Gln-Arg-Tyr-Leu-Asn-Ala-Lys-OH, which is critical for its specific receptor binding profile.
- Purity Standard: Minimum 98% by HPLC analysis, with premium batches reaching 99.5% for research-grade applications.
- Solubility: Readily soluble in water and phosphate-buffered saline (PBS) at concentrations up to 10 mg/mL, with gentle warming if needed.
- Storage Conditions: Lyophilized powder stable for 24 months at -20°C; reconstituted solutions should be used within 7 days at 4°C.
- Appearance: White to off-white powder, free from visible particulates or discoloration.
- Endotoxin Level: Less than 1 EU/mg, suitable for cell culture and in vivo research protocols.
Industry data from the Peptide Research Consortium (2023) indicates that ARA 290 peptide with a purity above 98% shows a 40% higher binding affinity to the innate repair receptor (IRR) compared to lower-grade alternatives, making purity a non-negotiable parameter for reproducible results.
Manufacturing & Quality Control
The manufacturing of ARA 290 peptide follows a rigorous solid-phase peptide synthesis (SPPS) process, utilizing Fmoc chemistry to ensure high coupling efficiency and minimal side reactions. Each batch is produced in a cGMP-compliant facility, with strict environmental controls to prevent contamination. The production process includes automated synthesis, cleavage, and precipitation steps, followed by lyophilization to yield the final powder.
Quality control is multi-layered. After synthesis, the crude peptide undergoes reversed-phase high-performance liquid chromatography (RP-HPLC) for initial purity assessment. The target peak is collected, and the purified product is analyzed again to confirm the 98%+ threshold. Mass spectrometry (MS) is used to verify the molecular weight, ensuring the correct sequence has been assembled. Additionally, amino acid analysis (AAA) provides a quantitative check of each residue.
- Third-Party Testing: Every batch is sent to an independent ISO 17025 accredited laboratory for independent HPLC and MS verification.
- Certificate of Analysis (COA): Provided with each shipment, detailing purity, molecular weight, appearance, and endotoxin levels.
- Stability Studies: Accelerated stability testing at 40°C/75% RH for 4 weeks confirms product integrity under stressed conditions.
- Batch Consistency: Inter-batch variability is less than 2% for purity and less than 1% for peptide content, ensuring reproducible performance.
- Packaging: Supplied in sterile, vacuum-sealed vials with desiccant to prevent moisture absorption.
Commercial Application Scenarios
ARA 290 peptide is utilized across multiple B2B sectors due to its unique non-erythropoietic profile. In cosmetic formulation, it is incorporated into advanced serums and creams targeting skin barrier support and resilience. The peptide's ability to interact with the innate repair receptor makes it a valuable ingredient for products aimed at environmental stress recovery. Formulators typically use concentrations between 0.1% and 1.0% in water-based systems.
In laboratory research, ARA 290 is a standard tool for studying neuroprotection, inflammation modulation, and tissue repair mechanisms. It is frequently used in cell-based assays to evaluate receptor activation and downstream signaling pathways. Bulk wholesale buyers include contract research organizations (CROs) and academic labs that require consistent, high-purity material for multi-year studies.
- Cosmetic Formulation: Used in anti-aging and barrier-support creams, often combined with hyaluronic acid and ceramides.
- Lab Research: Applied in neuronal cell cultures and animal models for neuroprotection studies.
- Bulk Wholesale: Supplied in 1g, 5g, and 10g quantities for large-scale research programs.
- Custom Synthesis: Available for modified sequences or specific labeling requirements.

Bulk Purchase Selection Guide
When sourcing ARA 290 peptide in bulk, buyers must navigate common pitfalls to ensure they receive a product that meets their technical requirements. One frequent issue is the misrepresentation of purity levels, where suppliers claim 98% but deliver material with lower actual purity. Always request a Certificate of Analysis (COA) from an independent lab before committing to large orders. Another pitfall is inadequate packaging, which can lead to moisture absorption and degradation during transit.
Selection standards should include verification of the supplier's manufacturing certifications, such as cGMP or ISO 9001. Additionally, confirm that the peptide is shipped with cold chain logistics if required, especially for reconstituted forms. A buyer checklist can streamline the evaluation process:
- Request COA: Ensure it includes HPLC, MS, and endotoxin data from a third-party lab.
- Check Packaging: Look for vacuum-sealed vials with desiccant and tamper-evident seals.
- Verify Storage: Confirm the supplier maintains proper cold storage for bulk inventory.
- Ask for Samples: Test a small batch before placing a large order.
- Review Lead Times: Ensure the supplier can meet your delivery schedule without compromising quality.
