    Synthetic
  • Additional Information
    This peptide named NEI (N for neuropeptide, E for Glu and I for Ile) is processed from pro-MCH. It has been reported that rat MCH may act as a central corticotropin inhibitory factor involved in the circadian rhythmicity of plasma ACTH levels in the rat while NEI antagonizes its action.
  • Storage Guidelines
    Ideally Neuropeptide-glutamic acid-isoleucine, Neuropeptide EI (human, mouse, rat) should be stored in a freezer at or below -9C. Neuropeptide-glutamic acid-isoleucine, Neuropeptide EI (human, mouse, rat) should be refrigerated after reconstitution. For more details, please refer to the manual:Handling and Storage of Synthetic Peptides

  • About TFA salt

    Trifluoroacetic acid (TFA) is a strong acid, which is commonly used to cleave synthesized peptides from solid-phase resins and is also used to improve HPLC performance in the peptide purification step. By default, custom peptides are delivered as lyophilized TFA salts, and can contain as much as 10-45% TFA.

    TFA in custom peptides can cause inexplicable discrepancies in subsequent assay data. For instance, TFA in nM concentrations has been shown to interfere with cellular assays, inhibiting cellular proliferation in some instances, and increasing cell viability in others . It has also been found to be an unintended allosteric modulator of the glycine receptor, GlyR.

    TFA Removal Service is recommended for:

    • Peptides that will be used in cellular assays
    • Peptides that will be used as APIs or in manufactured products
    • For hydrophilic peptides containing numerous basic residues
