ARA-290 (16mg)
ARA-290 is an eleven-residue peptide derived from the helix B surface of erythropoietin. It engages the innate repair receptor without the erythropoietic activity of full-length EPO, which is what makes it useful for separating the two pathways.

About ARA-290 (16mg)
The eleven residues correspond to a surface that is inaccessible in intact EPO, which is why the fragment separates tissue protection from erythropoiesis where the parent hormone cannot.
Like everything in the Peptides range, this vial is lyophilized, sealed, and accompanied by third-party purity documentation for its batch.

Handling, reconstitution and storage
Store the sealed vial of lyophilized ARA-290 at -20°C, protected from light. Allow it to reach room temperature before opening so that moisture does not condense onto the powder.
Reconstitute with bacteriostatic water directed down the inside wall of the vial rather than onto the cake, and swirl instead of shaking — mechanical agitation is the most common cause of degradation in peptide handling. Keep reconstituted solution at 2-8°C and validate its working life for your own assay conditions.
Frequently asked questions
- How is ARA-290 (16mg) supplied and stored?
- It ships as a lyophilized powder in a sealed vial. Store the lyophilized product at -20°C protected from light; once reconstituted with bacteriostatic water, keep it refrigerated at 2-8°C and use it within the window your protocol validates.
- Is a certificate of analysis available?
- Yes. Every batch is independently tested by a US laboratory and verified to exceed 99% purity by HPLC/MS. Request the COA for your batch number and we will send the report.
- How long does delivery take?
- Orders dispatch within two business days. Delivery is free within the USA on orders over $200.
- Can ARA-290 (16mg) be used in humans or animals?
- No. This product is sold strictly for research, laboratory and analytical purposes. Human and animal consumption is prohibited.
