General guidance for this class

Reference standards in the Neuropeptides class are typically shipped as lyophilized powder and stored desiccated at −20 °C protected from light. Once reconstituted in bacteriostatic water or the assay-appropriate buffer, aliquot and store at −80 °C to minimize freeze–thaw cycles. Confirm handling requirements against your institutional biosafety and radiation protocols before use.

Mechanism & research applications

Orexin A, human sits within the Neuropeptides research class (CPC reference OREX-001). Neuropeptides bind GPCRs expressed on central and peripheral neurons — modulating cAMP, calcium, and β-arrestin signaling to shape neurotransmission, network excitability, and behavior. Investigators typically incorporate Orexin A, human as a reference standard, tool ligand, or substrate in the assay contexts listed above. Radioligand binding, cAMP HTRF, calcium mobilization, and in vivo behavior assays.

Studied for

  • GPCR receptor-binding and functional profiling
  • Behavioral pharmacology (rodent models)
  • Pain, mood, and anxiety-circuit research
  • Neuroendocrine feedback studies

Frequently asked

What is Orexin A, human?

Orexin A, human (CPC catalog code OREX-001) is a synthetic neuropeptide receptor ligand in the neuropeptides category. It is provided as a lyophilized ~1 mg vial for in-vitro research use only.

What is Orexin A, human studied for?

Published and internal research programs use Orexin A, human as a reference standard in neuropeptides workflows — for example, gpcr receptor-binding and functional profiling and behavioral pharmacology (rodent models). Human clinical evidence is not established.

Is Orexin A, human FDA-approved for human use?

No. Orexin A, human is a research-grade reference peptide and is not approved by the FDA or any national regulator for human or veterinary therapeutic use. It is offered exclusively for in-vitro laboratory research and does not ship to the United States for consumer use.

How is Orexin A, human typically used in the lab?

In a neuropeptides workflow, Orexin A, human is reconstituted in sterile buffer or DMSO (solubility-dependent) and applied in the researcher's chosen assay format. Radioligand binding, cAMP HTRF, calcium mobilization, and in vivo behavior assays.
