Description

This ARA-290 nasal spray supplies ARA-290, also named cibinetide (molecular formula C51H84N16O21, molecular weight 1257.3 g/mol), an 11-residue peptide, as a ready-to-use intranasal solution for laboratory research. ARA-290 is derived from the helix-B tissue-protective domain of erythropoietin and, in the research literature, is an agonist at the innate repair receptor (an EPO receptor and CD131 complex) that does not stimulate red blood cell production, unlike the parent hormone.

ARA-290 nasal spray in tissue-protection research

The pre-measured spray keeps intranasal ARA-290 research consistent, with a coefficient of variation under 5% across the bottle. ARA-290 is studied for its non-erythropoietic profile, which lets researchers separate tissue-protective signaling from the red-cell effects of erythropoietin. The peptide is also examined in models of neuropathic pain and inflammation. Every batch ships with an HPLC chromatogram and mass-spectrum identity confirmation of the 1257.3 g/mol target.

ARA-290 nasal spray storage and handling

Store the sealed bottle at 2 to 8 C, out of direct light, where the solution stays stable for about 12 months. Careful ARA-290 nasal spray storage means letting a cold bottle reach room temperature before priming, avoiding long periods of warmth, and logging each actuation for a clean research record.

Frequently asked questions

What is ARA-290 (cibinetide)?

ARA-290, or cibinetide, is an 11-amino-acid peptide (CAS 1208243-50-8) copied from the tissue-protective helix-B region of erythropoietin. In research it is studied as a non-erythropoietic innate repair receptor agonist. This product is that peptide in a research-grade nasal spray, not a medicine.

How should ara-290 nasal spray be stored?

Store the sealed bottle at 2 to 8 C, away from direct light. Under these conditions the metered spray solution stays stable for about 12 months. Keep it out of reach of children and label it clearly as a research material, not for consumption.

What purity is ara-290 nasal spray?

Every batch is verified at 99% or higher purity by HPLC, with molecular identity confirmed by mass spectrometry at an independent ISO 17025-accredited laboratory. A batch-specific certificate of analysis ships with each order so you can check the numbers against your own standards.

Is ara-290 nasal spray for human use?

No, ara-290 nasal spray is sold for laboratory research use only and is not for human or veterinary consumption. It is not a drug or supplement and has not been evaluated by the FDA. Handle it under standard laboratory safety practice.
