ARA-290Research-Grade Peptide · Lab-Verified Purity

ARA-290 is a research-grade synthetic peptide supplied by ProSource Labs, a trusted US-based direct-to-researcher retail store in the Healing & Recovery category. All lab-verified ARA-290 vials are synthesized in a controlled laboratory environment, lyophilized (freeze-dried) for long-term stability, and sealed in tamper-evident vials before undergoing third-party analytical testing.

ARA-290 is offered strictly for laboratory research applications — including in vitro assays, cell-culture experiments, receptor-binding characterization studies, biochemical pathway investigation, and preclinical mechanism-of-action work in animal models. Not intended for and not approved for human or veterinary consumption. Every ARA-290 order ships with a batch identifier for full traceability back to its manufacturing lot, HPLC purity report, and Certificate of Analysis (COA).

ProSource Labs supplies ARA-290 in the following available vial sizes: 10mg. Each ARA-290 vial contains pure lyophilized peptide — no fillers, no bulking agents. Product SKU references: ARA-10MV.

Batches are characterized by ESI mass spectrometry to confirm molecular weight against the theoretical value, with amino-acid sequence confirmation on selected QA lots. Peptide content assay distinguishes net peptide mass from residual counter-ion salt.

Lyophilized ARA-290 vials should be stored at -20°C (or colder) in a laboratory freezer, inside the sealed factory container. Minimize warm-up cycles — move only the specific vial needed for a given experiment out of frozen storage at a time.

All laboratory handling of ARA-290 should follow the receiving institution's SOPs and applicable peer-reviewed protocols relevant to the researcher's specific experimental question. ProSource Labs does not publish end-user preparation or usage instructions.

Every batch of ARA-290 released by ProSource Labs undergoes independent reverse-phase High Performance Liquid Chromatography (HPLC) — the industry-standard analytical method for this class of research compound. Target chromatographic purity is typically ≥ 99%.

Additional characterization may include ESI mass spectrometry for molecular weight confirmation, Karl Fischer titration for residual moisture, and appearance/solubility inspection. A batch-specific Certificate of Analysis (COA) is available on request through customer support after purchase.

Each production lot of ARA-290 is quarantined pending analytical release, tested against documented purity, identity, and moisture acceptance criteria, and only released to sellable inventory after passing every QA checkpoint. Batches that fail any single criterion are quarantined and never reach customer-facing inventory.

If a vial of ARA-290 you received from ProSource Labs ever fails your own institution's incoming QA testing, contact customer support at support@prosourcelabs.org — we retain samples of every batch for cross-verification.

ARA-290 is used in preclinical and cell-culture research within the Healing & Recovery category. Consult peer-reviewed literature relevant to your specific experimental question for detailed methodology.

ARA-290 vials ship in tamper-evident, moisture-resistant, cold-chain-friendly outer packaging from our Southern California distribution facility for fast US domestic delivery — typically 2-4 business days coast-to-coast, with expedited options available at checkout.

Every ARA-290 shipment is discreet — the outer packaging carries no product-specific branding or direct reference to the compound name inside, protecting researcher privacy. Tracking numbers are emailed automatically. For institutional or high-volume orders, dedicated wholesale pricing is available through the wholesale portal.
