ARA-290 10mg COA and lot verification
Each ARA-290 10mg lot ships with a third-party Certificate of Analysis that lists the lot identifier, the reversed-phase HPLC purity result and the mass-spectrometry identity confirmation for that batch. Match the lot number printed on the vial to the lot on the COA before the material is used in any in-vitro protocol; if the two do not match, contact us for the correct document.
What is ARA-290 10mg?
ARA-290 is a synthetic 11-amino-acid peptide derived from the helix-B domain of erythropoietin. Developed by Araim Pharmaceuticals (now Cibinetide), it activates the innate repair receptor (IRR) — a heteroreceptor of EPOR and CD131 — without binding the classical EPO receptor responsible for red-cell production.
ARA-290 for sale at Amino Fuel Labs means a 10 mg vial of ARA-290 (Cibinetide) at 99.2% HPLC purity, independently verified by an independent third-party lab and dispatched same-day from a USA facility with a batch-specific Certificate of Analysis in the box. ARA-290 is a innate-repair receptor agonist compound used in neuropathic pain, tissue-protection, and inflammation research. When researchers go looking for ARA-290 for sale, the priorities are documented purity, batch-traceable third-party COAs, and reliable USA cold-chain shipping — and every vial we ship is engineered around those three guarantees.
How ARA-290 works
ARA-290 (Cibinetide) is an 11-amino-acid erythropoietin-derived peptide that selectively activates the innate-repair receptor (IRR — EPOR/βcR heterodimer), driving tissue-protective and anti-inflammatory signaling without erythropoietic side effects. This mechanistic profile is why ARA-290 is one of the most-requested research compounds in the innate-repair receptor agonist category, and why purity verification matters so much — even small impurity differences can alter receptor-binding data in published in-vitro work.

Testing method
Reversed-phase HPLC with mass-spectrometry identity confirmation
Every lot of ARA-290 we list is supplied with a lot-matched Certificate of Analysis. Identity is confirmed by mass spectrometry and purity is measured by reversed-phase HPLC, with both results reported for the specific lot printed on the vial label. The certificate travels with the order, so the documentation can be reconciled against the material on receipt. Purity is a lot-specific value: read the figure on the certificate that matches your vial rather than treating it as a fixed product attribute. Supplied for laboratory research use only.
ARA-290 shipping and support
Orders placed before 2:00 PM ET ship the same business day from our USA facility. Standard delivery lands in 2–4 business days; expedited and priority options are available at checkout. Every order over $300 ships free, and we use insulated packaging with a cold pack for temperature-sensitive compounds. If anything arrives damaged or off-spec we replace it — no restocking fees, no upsell. Customer support is human-staffed and replies to research and order emails in under one hour during business days.
ARA-290 10mg FAQ
What is ARA-290 studied for?
ARA-290 appears in laboratory research covering neuropathy treatment, diabetic complications, wound healing. Every reference describes in-vitro or preclinical study models, not outcomes in people.
Does ARA-290 include a Certificate of Analysis?
Yes. Each ARA-290 lot ships with a batch-specific third-party Certificate of Analysis reporting 99.2% purity by reversed-phase HPLC with mass-spectrometry identity confirmation. The COA linked on this page matches the lot number printed on the vial.
What form does ARA-290 arrive in and how is it stored?
ARA-290 is supplied as lyophilized powder in a sealed vial with its lot documentation. Store at -20°C (Freezer), protect the vial from light and avoid repeated freeze–thaw cycles.
Does HPLC purity tell me the net peptide content?
No. HPLC area-percent purity and net peptide content are different measurements. Review the report for each value rather than treating them as interchangeable. Read about peptide purity versus net content.
What purity is your ARA-290 for sale?
Every batch of ARA-290 for sale at Amino Fuel Labs is independently HPLC-verified at 99.2% purity with mass-spectrometry identity confirmation by an independent third-party lab.
What size is the ARA-290 vial?
Our standard ARA-290 for sale is a single 10 mg lyophilized vial. The vial ships in an insulated mailer with a cold pack by default.
How fast does ARA-290 ship?
All ARA-290 orders ship same-day from our USA fulfillment center on orders placed before 2:00 PM ET, Monday through Friday. Standard delivery is 2–4 business days.
Why is ARA-290 used instead of EPO?
ARA-290 separates the tissue-protective effects of EPO (via the IRR) from its erythropoietic effects (via the EPOR homodimer). Researchers get the neuroprotection without raising hematocrit.
What's the strongest published evidence for ARA-290?
Phase II trials in sarcoidosis-associated small-fiber neuropathy showed significant reduction in neuropathic pain scores and improvements in intra-epidermal nerve fiber density.
Do you provide a COA?
Yes. ≥99.2% HPLC purity, mass-spec confirmation, endotoxin testing — included on every batch.
