What Met-Enkephalin is studied for

  • Opioid-receptor binding and selectivity profiling
  • β-arrestin recruitment and biased-agonism studies
  • Analgesic mechanism research
  • Tolerance and dependence models

Mechanism of action

Met-Enkephalin sits within the Opioid research class (CPC reference ENKP-006). Opioid peptides bind μ, δ, and κ receptors — Gi/o-coupled GPCRs that inhibit adenylate cyclase, activate GIRK channels, and modulate calcium currents to produce analgesia, tolerance, and reward-circuit effects. Investigators typically incorporate Met-Enkephalin as a reference standard, tool ligand, or substrate in the assay contexts listed above. GTPγS binding, cAMP HTRF, and β-arrestin PathHunter assays.

Frequently asked questions

What is Met-Enkephalin?

Met-Enkephalin (CPC catalog code ENKP-006) is a synthetic opioid-receptor research peptide in the opioid category. It is provided as a lyophilized ~1 mg vial for in-vitro research use only.

What is Met-Enkephalin studied for?

Published and internal research programs use Met-Enkephalin as a reference standard in opioid workflows — for example, opioid-receptor binding and selectivity profiling and β-arrestin recruitment and biased-agonism studies. Human clinical evidence is not established.

Is Met-Enkephalin FDA-approved for human use?

No. Met-Enkephalin 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 Met-Enkephalin typically used in the lab?

In a opioid workflow, Met-Enkephalin is reconstituted in sterile buffer or DMSO (solubility-dependent) and applied in the researcher's chosen assay format. GTPγS binding, cAMP HTRF, and β-arrestin PathHunter assays.

How should Met-Enkephalin be stored?

Store lyophilized at −20 °C. Handle as Schedule research reagents where applicable. Follow your institution's standard operating procedures for handling synthetic peptides.

Where does the Met-Enkephalin product page point to?

This kindr reference page mirrors CPC Scientific's catalog metadata for ENKP-006. The upstream reference sheet — including sequence, purity, MW, and application notes where published — is linked from the buy panel. All orders placed on kindr Peptides ship internationally under research-use terms only.

What quality specifications apply to Met-Enkephalin?

Research-grade peptides in the CPC catalog are synthesized by solid-phase peptide synthesis (SPPS), purified by preparative RP-HPLC, and characterized by analytical HPLC and mass spectrometry. Typical purity is ≥95%; certificate of analysis is available on request.
