  • Additional Information
    Pseudin-2 is a cationic alpha-helical peptide originally isolated from the skin of the paradoxical frog Pseudis paradoxa on the basis of its antimicrobial activity. The peptide stimulated insulin secretion from BRIN-BD11 cells by a Ca2+-independent mechanism. CD studies showed that the pseudins belong to amphipathic alpha-helical antimicrobial peptides. MOA: It probably interacts with membranes (pore formation) and also binds to RNA (inhibition of protein synthesis) (Park SC et al. 2010 BBA in press). Pseudin-2 has Antibacterial, Antifungal activity. Pseudin-2 was found in Paradoxical frog, Pseudis paradoxa, South America.
  • Storage Guidelines
    Ideally Pseudin-2 peptide should be stored in a freezer at or below -9C. Pseudin-2 peptide 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
