Description

ARA-290 Peptide Overview

ARA-290 Peptide is a synthetic peptide derived from a specific region of erythropoietin (EPO). Unlike erythropoietin itself, ARA-290 is designed as a non-hematopoietic research peptide and has been investigated in preclinical research involving tissue-protective signaling, inflammation-related pathways, and cellular responses.

ARA-290 is also known in scientific literature as an EPO-derived tissue-protective peptide. Its structure and biological activity have made it an interesting compound for researchers investigating mechanisms associated with the innate repair receptor and related cellular signaling pathways.

ARA-290 research is primarily experimental and preclinical. Results observed in laboratory or animal models should not automatically be interpreted as demonstrated therapeutic effects in humans.

Molecular Formula, Molecular Weight & Sequence

Commonly reported specifications for ARA-290 Peptide include:

Important specification note

ARA-290 is frequently described in the literature as an 11-amino-acid peptide derived from erythropoietin, but commercial and database records can differ in how the peptide sequence, terminal modifications, and chemical form are represented.

Because of this, the safest professional approach for your product page is to use the exact sequence, molecular formula, molecular weight, and terminal modifications shown on your manufacturer’s COA rather than publishing an unverified molecular specification.

This is particularly important for peptide products because terminal modifications, salts, counterions, and formulation can change the reported molecular mass.

For your product page

Before publishing the specifications, ensure that:

Product label → sequence → formula → molecular weight → COA → mass spectrometry

all refer to the same chemical material.

Purity

A suitable research-grade specification for ARA-290 may be:

Purity: ≥98% by HPLC

The actual purity should always be confirmed using the batch-specific Certificate of Analysis (COA).

Depending on the testing package, documentation may include:

• HPLC purity percentage
• HPLC chromatogram
• Mass spectrometry
• Calculated molecular weight
• Observed molecular weight
• Lot/batch number
• Testing date
• Net peptide quantity

Researchers should evaluate the analytical results for the exact batch they receive rather than relying solely on a general product-page purity statement.

Appearance

Appearance: White to off-white lyophilized powder.

ARA-290 may be supplied as a lyophilized material for controlled laboratory storage.

Small differences in powder texture or color may occur because of manufacturing, drying, formulation, or batch conditions.

However, visual appearance cannot establish peptide identity or purity. When confirmation is required, researchers should rely on appropriate analytical methods such as HPLC and mass spectrometry.

Available Vial Sizes

ARA-290 Peptide can be offered in different research quantities depending on laboratory requirements and available inventory.

Common vial sizes include:

• 2 mg
• 5 mg
• 10 mg
• 20 mg

For many individual laboratory projects, 5 mg and 10 mg formats are convenient research quantities.

Larger quantities may be suitable for laboratories conducting repeated experiments or analytical research.

Always state the net peptide quantity per vial clearly on the product page and product label.

Storage Recommendations

Proper storage helps maintain the quality of lyophilized peptide material.

For lyophilized ARA-290:

• Follow the storage temperature specified in the applicable product documentation.
• Keep the vial tightly sealed.
• Protect the peptide from moisture.
• Minimize exposure to excessive heat and direct light.
• Avoid unnecessary temperature cycling.
• Allow a cold vial to equilibrate appropriately before opening to minimize condensation.

Controlled frozen storage may be appropriate for long-term storage when supported by applicable stability information.

Important: Exact storage requirements can vary according to peptide formulation, packaging, and stability data. The storage instructions supplied with the specific batch should take priority.

Reconstitution Information

ARA-290 Peptide is supplied as a lyophilized research material. When reconstitution is required for a laboratory experiment, researchers should select a compatible solvent and concentration according to their validated experimental protocol.

General laboratory considerations include:

1. Allow the sealed vial to reach a suitable temperature before opening.
2. Use a compatible laboratory-grade solvent.
3. Introduce the solvent carefully.
4. Avoid unnecessarily vigorous agitation.
5. Allow sufficient time for dissolution.
6. Minimize excessive foaming.
