  • Additional Information
    In one study where this peptide was labeled with 125I, it was found to bind specifically and with high affinity to αvβ3 receptors on neovascular blood vessel sections of different major human cancers. The integrin alpha(IIb)beta(3)-specific cyclic hexapeptide contains an Arg-Gly-Asp (RGD) sequence.
  • Storage Guidelines
    Ideally c(RGDfK) should be stored in a freezer at or below -9C. c(RGDfK) 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
