  • Additional Information
    Derived from N-terminal domain of unacetylated histon H2A and released by a pepsin. Also detected in bovine, porcine, and human stomach (Found in multiple species, FIMS). Its location on mucosal surfaces of vertebrate stomach plays an important role in innate defense against invading microbes. Updated 11/2011 GW. Buforin I has Antibacterial, Antifungal activity. Buforin I was found in stomach, Bufo bufo gargarizans, Asia; Also in: Homo sapiens; Bos taurus; Sus scrofa.
  • Storage Guidelines
    Ideally Buforin I should be stored in a freezer at or below -9C. Buforin I 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
