ARA-290 (Cibinetide)

Description

ARA-290 (Cibinetide) is a research-grade peptide reagent for laboratories working on tissue repair, neuropathy and innate immune signalling models. Like the rest of our research peptides, Canada-based buyers receive it as a lyophilized 16 mg vial with a certificate of analysis matched to the exact batch in the box. It is sold strictly for in-vitro laboratory research and is not for human or veterinary use.

Overview

ARA-290 is a short, non-erythropoietic peptide sequence derived from the helix B region of erythropoietin — the part of the molecule associated in the literature with tissue-protective signalling through the innate repair receptor rather than with red blood cell production. That structural distinction is the whole reason the peptide exists as a research tool: it lets investigators probe the tissue-protective arm of EPO signalling in isolation, without the haematopoietic activity that complicates work with full-length erythropoietin. Each unit is supplied as a sealed vial of lyophilized powder containing 16 mg of peptide, to be reconstituted by the researcher in a solvent appropriate to the assay. Single vials and boxes of ten are available, so a lab can order a working amount for method development or a full box for a planned series of experiments without waiting on a second shipment.

What it is known for

Buyers know ARA-290 as the non-erythropoietic EPO-derived peptide — the reagent chosen when the research question concerns tissue protection and repair signalling rather than erythropoiesis. What separates one supplier’s vial from another’s is not the sequence but the evidence behind it, and that is where this listing is built to compete: every batch goes to Janoshik, an independent analytical laboratory, for HPLC purity and mass spectrometry identity, and the resulting certificate is matched to the batch you actually receive rather than to a representative lot from months ago.

Key features

• 11-amino-acid EPO helix B derivative — Gives researchers the tissue-protective signalling motif in a small, synthetically defined form — far easier to handle, dose and reproduce in vitro than recombinant full-length erythropoietin.
• Non-erythropoietic by design — Lets experiments isolate innate repair receptor activity without the confounding haematopoietic effects associated with the parent hormone.
• Independent third-party analysis by Janoshik — Purity and identity are verified by a lab with no commercial stake in the result, so your data rests on a characterized reagent rather than a supplier’s own word.
• HPLC purity plus MS identity on every batch — HPLC tells you how much of the vial is the target peptide; mass spectrometry confirms it is the right peptide. You need both before a reagent belongs in a controlled experiment.
• Batch-matched certificate of analysis — The paperwork corresponds to the lot number on your vial, which is what a supervisor, grant auditor or reviewer will ask for when you cite reagent provenance.
• Lyophilized powder format — The dry state is the stable state for peptides. You control the solvent, the concentration and the aliquoting schedule to suit your protocol.
• 16 mg fill, single vial or box of ten — Enough material for a meaningful working stock, with a bulk option that keeps a longer study on one lot number and removes batch-to-batch variability from your results.
• Cold-stored and shipped domestically from Canada — Shorter transit under tracking means less time at ambient temperature and no customs hold between order and bench.

Benefits

• You can trace every result back to a specific, independently verified lot rather than an unverified generic vial.
• Ordering a box of ten keeps a full experimental series on a single batch, so reagent variability is not a competing explanation for your findings.
• Domestic Canadian shipping with tracking shortens transit and avoids international clearance delays.
• Lyophilized supply gives you full control over reconstitution buffer, concentration and aliquot size.
• Discreet, tracked packaging suited to institutional and private lab receiving.

Specifications

Typical applications

• In-vitro investigation of innate repair receptor and EPO-related tissue-protective signalling pathways
• Cell-culture models of inflammation and tissue repair
• Comparative studies against erythropoietin or other EPO-derived peptide fragments
• Receptor binding, signalling and dose-response characterization work
• Analytical method development and reference work requiring a characterized peptide standard

Important information

• Research use only. Not a drug, supplement, food or cosmetic. Not for human or veterinary use, ingestion or administration, and not intended to diagnose, treat, cure or prevent any disease.
• Keep the vial cold and sealed until use; lyophilized peptide is more stable than peptide in solution.
• Reconstitute in a solvent appropriate to your assay and handle under aseptic technique. Prepare single-use aliquots where your protocol allows to avoid repeated freeze–thaw cycles.
• Check the lot number on the vial against the certificate of analysis before you begin, and record it in your notes.
• Allow the vial to reach room temperature before opening to reduce condensation on the powder.
• Ordering for a multi-week study? Consider a box of ten so the entire series runs on one lot.

Common questions

What makes ARA-290 different from erythropoietin in research work?

ARA-290 corresponds to the helix B region of erythropoietin and is non-erythropoietic — it is used to study the tissue-protective signalling arm of EPO biology without the red-cell-stimulating activity of the full hormone. Practically, it is also a small synthetic peptide rather than a recombinant glycoprotein, which makes it simpler to handle and more reproducible between experiments.

How much peptide is in a vial?

Each vial contains 16 mg of lyophilized ARA-290. You can order a single vial or a box of ten.

Who performs the testing, and can I see the results?

Purity by HPLC and identity by mass spectrometry are performed by Janoshik, an independent analytical laboratory. A certificate of analysis matched to your batch is available.

How should I store it once it arrives?

Store the sealed vial cold. Once reconstituted, follow your lab’s standard practice for peptide solutions — keep it cold, use it promptly and avoid repeated freeze–thaw cycles by aliquoting.

Does it come reconstituted or with a solvent?

No. It ships as dry lyophilized powder so you choose the solvent and concentration that suit your protocol. Reconstitution is performed in your own lab.

Can I buy this for personal use?

No. This is a laboratory reagent sold for in-vitro research only. It is not for human or veterinary use in any form.

In summary

A characterized, independently tested ARA-290 reagent in a 16 mg lyophilized vial, with the certificate of analysis tied to the batch in your hand and a short domestic shipping route from Canada to your bench. If your work depends on knowing exactly what is in the vial, that documentation is the point.
