  • Additional Information
    The antimicrobial peptide zp37 (GIKAKIIIKIKK-NH2), which possesses a helical structure, was found to exhibit a minimum inhibitory concentration (MIC) value of 16 μM on E. coli O157:H7, effectively killing such strain in vitro and reducing its population size by 94.7% in sprouts upon storage for seven days. In sprouts, zp37 treatment reduced 94.7% E. coli O157:H7 upon storage for 7 days. zp37 caused membrane depolarization and weak membrane permeabilization. zp37 bound to the DNA of E. coli O157:H7, causing DNA aggregation and precipitation.
  • Storage Guidelines
    Ideally Antimicrobial peptide zp37 should be stored in a freezer at or below -9C. Antimicrobial peptide zp37 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
