  • Additional Information
    The Cu²⁺ complex of this soluble amyloid β-protein fragment showed significant oxidative activities toward the catechol-like substrate 1,2,3-trihydroxylbenzene (pyrogallol) and plasmid DNA cleavage. The N-terminal Aβ fragments Aβ1-14 (H-7372), Aβ1-15 (H-6368), and Aβ1-16 are elevated in cell media and in CSF in response to γ-secretase inhibitor treatment. The fragments can serve as biomarkers in clinical studies of the effect of such inhibitors.
  • Storage Guidelines
    Normally, this peptide will be delivered in lyophilized form and should be stored in a freezer at or below -20 °C. 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
