Physical Properties
ARA-290 is a 16-amino-acid synthetic peptide modeled after the helix-B surface region of erythropoietin. The truncated sequence preserves key structural elements while omitting the full erythropoietin protein framework. Its compact size supports efficient solubility and ease of handling in laboratory environments. Lyophilized formulation enhances stability during storage, while protection from light, moisture, and repeated freeze–thaw cycles helps maintain peptide integrity for research and analytical applications.

Frequently Asked Questions
What is ARA-290?
ARA-290 is a synthetic EPO-derived peptide designed to selectively activate non-hematopoietic signaling pathways. It is studied in laboratory and preclinical environments to explore tissue protection and cellular repair mechanisms.
What is ARA-290 commonly researched for?
In experimental research settings, ARA-290 is investigated for:
-
Tissue-protective signaling mechanisms
-
Inflammatory response modulation
-
Neuroprotective and peripheral nerve research models
-
Cellular stress and repair pathway studies
All research use is preclinical and exploratory.
Is ARA-290 the same as erythropoietin (EPO)?
No. While ARA-290 is derived from a segment of erythropoietin, it does not stimulate red blood cell production in research models. It is specifically engineered to isolate tissue-protective signaling effects separate from erythropoiesis.
How is ARA-290 supplied?
ARA-290 is typically supplied as a lyophilized (freeze-dried) powder in sealed research vials. Lyophilization enhances stability during storage and shipment prior to laboratory preparation.
How should unreconstituted ARA-290 be stored?
Lyophilized ARA-290 should be stored:
-
Long-term: −20 °C to −80 °C
-
Short-term: 2–8 °C
Vials should remain sealed and protected from light and moisture.
How should reconstituted ARA-290 be handled and stored?
Once reconstituted:
-
Store at 2–8 °C for short-term laboratory use
-
For extended storage, aliquot and freeze at −20 °C or below
-
Minimize freeze–thaw cycles using single-use aliquots
-
Mix gently; avoid vigorous agitation
Does ARA-290 require a Certificate of Analysis (COA)?
Yes. A Certificate of Analysis (COA) should be available for each batch, confirming identity, purity, and analytical testing results to support research quality and traceability.
Is ARA-290 FDA-approved?
No. ARA-290 is not FDA-approved as a drug, supplement, or therapeutic product. It is sold exclusively as a research compound and must not be marketed or used for diagnostic, therapeutic, or consumption purposes.
