This sequence carries terminal or reporter modifications (NH2), so no molecular formula or weight is published here — the modified mass must come from the lot certificate of analysis. Residue composition and charge describe the peptide backbone only. Composition figures above are derived arithmetically from the published sequence for the unmodified free peptide. Salt forms (commonly trifluoroacetate or acetate), amidation, and other modifications shift the observed mass — always reconcile against the current lot certificate of analysis.

Handling, storage & reconstitution

Upstream storage
-20 ± 5 °C

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

Mastoparan X sits within the Neuropeptides research class (CPC reference NEUP-115). 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 Mastoparan X 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 Mastoparan X?

Mastoparan X (CPC catalog code NEUP-115) 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 Mastoparan X studied for?

Published and internal research programs use Mastoparan X 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 Mastoparan X FDA-approved for human use?

No. Mastoparan X 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 Mastoparan X typically used in the lab?

In a neuropeptides workflow, Mastoparan X 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.
