  • Description
    Active against E. coli K12, E. coli, B. megoturium (lethal conc 0.3 uM), S. typhimurium, Strep. pyogmes, A. calccouceticus (lethal conc 1-3 uM), and B. subti (15 uM). MOA: it probably binds to DNA (Boman HG et al. 1993 Infect Immun 61: 2978-84). In vitro, PR-39 retarded DNA migration in the 0.8% agarose gel (Baumann A et al., 2014). Updated 8/2014. PR-39 has Antibacterial activity. The source of PR-39 is Pig, Sus scrofa.

  • About TFA salt

    Trifluoroacetic acid (TFA) is a common counterion from the purification process using High-Performance Liquid Chromatography (HPLC). The presence of TFA can affect the peptide's net weight, appearance, and solubility.

    Impact on Net Weight: The TFA salt contributes to the total mass of the product. In most cases, the peptide content constitutes >80% of the total weight, with TFA accounting for the remainder.

    Solubility: TFA salts generally enhance the solubility of peptides in aqueous solutions.

    In Biological Assays: For most standard in vitro assays, the residual TFA levels do not cause interference. However, for highly sensitive cellular or biochemical studies, please be aware of its presence.
