ARA-290 10mg

ARA-290 10mg from Peptira is 10mg of ARA-290 in a sealed glass vial. ARA-290 is an erythropoietin-derived peptide. It’s intended for lab research only.

What is ARA-290?

ARA-290 (cibinetide) is an 11-amino-acid peptide based on a region of erythropoietin. It activates the tissue-protective receptor without stimulating red blood cell production.

Araim Pharmaceuticals developed it for small fiber neuropathy.

How ARA-290 works

Erythropoietin (EPO) has two jobs. It drives red blood cell production through one receptor, and it protects tissue through another, a complex of the EPO receptor with CD131.

ARA-290 mimics the small part of EPO that binds the tissue-protective receptor and leaves the red blood cell receptor alone. That lets researchers study EPO’s anti-inflammatory and nerve-protective effects without raising hematocrit.

Published ARA-290 studies

In a phase 2 study, Brines and colleagues reported that ARA-290 improved symptoms and corneal nerve fiber density in patients with sarcoidosis-related small fiber neuropathy.

Animal studies looked at nerve and kidney protection.

The primary literature is on PubMed, run by the US National Library of Medicine. Here’s a search for ARA-290 studies to start from.

ARA-290 10mg vs related compounds

Labs choosing ARA-290 10mg usually weigh it against a few close relatives. ARA-290 is an 11-amino-acid peptide from erythropoietin that protects tissue without raising red cells, while:

• BPC-157 is the 15-amino-acid repair peptide with the largest body of rodent research
• TB-500 is the 43-amino-acid actin-binding protein, studied for cell movement and wound repair
• KPV is a three-amino-acid alpha-MSH fragment studied for calming inflammation
• GHK-Cu is the copper-binding tripeptide studied for collagen and skin repair

These are the main peptides in repair research. Each covers a different step, from blood vessel growth and cell movement to calming inflammation and rebuilding the skin matrix. See them all on our healing and recovery peptides page.

ARA-290 10mg reconstitution and concentration

Here’s the math for 10mg of powder:

• 1mL of bacteriostatic water gives 10mg/mL
• 2mL of bacteriostatic water gives 5mg/mL
• 3mL of bacteriostatic water gives 3.33mg/mL

Choose the volume that suits your measurements. Mark the vial with the concentration and date so nobody has to guess later.

Use sterile bacteriostatic water, like our bacteriostatic water. Let the vial reach room temperature, run the water slowly down the inside of the glass, then roll the vial gently until the powder dissolves. Don’t shake it. Shaking can shear peptide chains.

ARA-290 10mg storage and shelf life

The dry powder keeps best cold and dark. A freezer at -20°C is right for long-term storage. After reconstitution, store it in the fridge at 2 to 8°C and finish it within roughly four weeks.

Running several vials at once? Our 10 vial kit case holds up to ten vials upright in separate wells under a clear lid, which keeps a fridge shelf tidy and the labels easy to read.

ARA-290 10mg quality notes

Every ARA-290 10mg vial carries a printed label with the compound name and amount, so you always know what you’re holding. If your lab needs batch paperwork for its records, contact Peptira support before you order and ask what’s available for the current batch.

Many labs run their own identity check when a new batch arrives. For peptides, purity is usually measured by HPLC, which separates a sample into its parts and reports the main compound as a share of the total. Mass spectrometry is often run alongside it to confirm the molecular weight.

Write the order date and the vial details into your lab notes. If a result looks odd later, you can tie it back to the exact material you used.

Ordering ARA-290 10mg for a full study

Work out the total amount before you order. Add up what each arm of the study uses across every time point, then divide by 10mg. Round up by one vial so a spoiled sample or a repeat run doesn’t stall the project.

Mix one vial at a time and keep the rest sealed in the freezer. Dry powder keeps far longer than solution, so there’s no reason to reconstitute everything at the start.

If you order more than one vial, check that the batch numbers match before you start. Running a whole study on one batch removes one variable.
