Buy ARA-290 Ireland

Buy ARA-290 in Ireland as a research-grade peptide available in 10mg and 16mg options. Also known as cibinetide, ARA-290 is a synthetic 11-amino-acid peptide derived from the helix-B region of erythropoietin (EPO). It has been investigated in laboratory research involving the innate repair receptor, EPO-related signalling, cellular protection and inflammatory pathways. ARA-290 is supplied strictly for laboratory and scientific research and is not intended for human or veterinary use.

What Is ARA-290?

ARA-290 is a synthetic peptide derived from the helix-B surface region of erythropoietin.

It is also known as:

• ARA-290
• ARA290
• Cibinetide
• pHBSP
• Pyroglutamate helix-B surface peptide

The commonly referenced cibinetide form is an 11-residue peptide with an N-terminal pyroglutamate. A commonly reported sequence is:

pGlu-Glu-Gln-Leu-Glu-Arg-Ala-Leu-Asn-Ser-Ser

This corresponds to the abbreviated sequence pEQLERALNSS. Current research references report a molecular weight of approximately 1,257.3 Da and CAS number 1208243-50-8 for this form.

ARA-290 was designed from the helix-B region of EPO to investigate signalling pathways associated with the innate repair receptor (IRR) rather than the classical erythropoietic EPO receptor pathway.

ARA-290 10mg & 16mg Ireland

Research Peptides Ireland offers ARA-290 in two labelled quantity options:

Both options contain the same named research peptide. The primary difference is the labelled quantity supplied.

The exact chemical form, purity and analytical results should always be confirmed using the documentation for the specific batch.

Buy ARA-290 10mg Ireland

The 10mg ARA-290 option provides a defined quantity of cibinetide for laboratory research.

Current research-product listings demonstrate 10mg ARA-290 presentations, with suppliers reporting HPLC purity testing and mass-spectrometry identity confirmation for individual batches.

Researchers should verify the actual lot-specific COA rather than relying solely on a general product-page specification.

Buy ARA-290 16mg Ireland

The 16mg ARA-290 option provides a larger labelled quantity than the 10mg presentation.

A current research-market listing specifically reports 16mg ARA-290 material with a vendor-published analytical record showing 99.3% purity. This result applies to that particular reported lot and should not be treated as the purity specification for every ARA-290 batch.

For Research Peptides Ireland, the actual batch COA should remain the authoritative source for the product’s analytical specifications.

ARA-290 Product Specifications

The chemical identifiers above correspond to the commonly referenced pyroglutamate/cibinetide form of ARA-290.

Important Identity Note

ARA-290 is sometimes described inconsistently across commercial research websites. Some listings use the glutamine-initiated sequence QEQLERALNSS, while references for registered cibinetide identify the N-terminal pyroglutamate form pEQLERALNSS.

For that reason, the actual manufacturer specification and batch-specific COA should determine the final sequence, molecular formula and molecular weight displayed for your product.

This is particularly important for a professional research website because the chemical identity should not be guessed from the product name alone.

ARA-290 Research Applications

ARA-290 has been investigated as a research tool for studying signalling associated with the innate repair receptor.

Research areas include:

• Innate repair receptor signalling
• EPO-derived peptide research
• EPOR/CD131 receptor biology
• Cellular signalling
• Neurobiology research
• Inflammatory signalling
• Tissue-protection research
• Peptide-receptor interactions
• EPO pathway research
• Comparative receptor pharmacology

Current research references describe ARA-290 as an EPO-derived peptide designed to investigate the non-erythropoietic signalling associated with the innate repair receptor.

ARA-290 and EPO Research

ARA-290 is derived from a region of erythropoietin (EPO), but it should not be confused with full-length EPO.

Full-length EPO is a larger glycoprotein hormone associated with erythropoietic signalling.

ARA-290 is a much smaller synthetic peptide designed around the helix-B surface of EPO.

This distinction is important when researching ARA-290 because the compound is specifically studied for signalling pathways separate from the classical red-blood-cell-producing activity associated with full-length EPO.

ARA-290 and the Innate Repair Receptor

One of the main scientific interests in ARA-290 is its relationship with the innate repair receptor (IRR).

The IRR is described in the literature as a receptor complex involving the erythropoietin receptor and the beta-common receptor/CD131.

ARA-290 was engineered to investigate this signalling system without reproducing the conventional erythropoietic activity associated with the classical EPO receptor.

This makes ARA-290 relevant to research examining:

Receptor Signalling

Researchers can investigate how an EPO-derived peptide interacts with receptor systems associated with cellular responses.

Cellular Research

ARA-290 can be used as a defined peptide material in controlled experimental models.

Neurobiology Research

Research has investigated ARA-290 in experimental models involving neural and neuropathy-related pathways.

Inflammatory Signalling

ARA-290 has also been investigated in experimental research involving inflammatory pathways and cellular signalling.

ARA-290 and Clinical Research

ARA-290 has progressed beyond purely laboratory research and has been investigated in early-stage human clinical research, including studies involving neuropathy-related conditions. Current research references describe its development as investigational rather than as an approved medicine.

This distinction should remain clear on the product page.

The fact that a compound has entered clinical research does not mean that a research-grade product sold online is an approved medicine or that experimental findings establish a particular medical benefit.

Research Peptides Ireland should therefore maintain the product’s research-use-only positioning.

ARA-290 Quality and Testing

Quality documentation is an important part of sourcing research-grade ARA-290.

Researchers should look for:

• Product identity
• Batch or lot number
• Reported purity
• HPLC analysis
• Mass-spectrometry identity confirmation
• Net quantity
• Chemical form
• Testing date
• Testing laboratory
• Certificate of Analysis

Current research suppliers publish examples of ARA-290 batches tested using HPLC and mass spectrometry, with individual lots reporting high analytical purity.

The result for a particular commercial batch should not be generalized to every ARA-290 product.

ARA-290 Certificate of Analysis

A Certificate of Analysis (COA) provides batch-specific information about the research material.

A useful ARA-290 COA may include:

• ARA-290/cibinetide identification
• Batch number
• Quantity
• HPLC purity
• Mass-spectrometry identity
• Molecular mass
• Testing date
• Testing laboratory
• Additional quality-control information

Researchers should match the lot number on the physical product to the corresponding COA.

For a peptide such as ARA-290, mass spectrometry can be particularly useful for confirming that the observed molecular mass corresponds to the expected peptide identity.

ARA-290 HPLC Testing

HPLC, or high-performance liquid chromatography, is commonly used to evaluate the chromatographic purity of research peptides.

Current ARA-290 product documentation includes examples of HPLC testing, with some suppliers reporting purity values above 99% for particular lots.

However, a generic statement such as “99% pure” should not replace the actual batch-specific analytical record.

For Research Peptides Ireland, the preferred approach is to associate the product with its current batch COA whenever analytical documentation is available.

ARA-290 10mg vs 16mg

The principal difference is the amount of research material supplied.

The chemical identity remains ARA-290, subject to confirmation by the relevant product documentation.

ARA-290 Ireland

Researchers looking to buy ARA-290 in Ireland can select between the 10mg and 16mg options according to their laboratory purchasing requirements.

Research Peptides Ireland is positioned around clearly identified research materials, product specifications and quality documentation.
