  • Description
    This peptide, originally isolated from the leech Hirudinaria manillensis, is a hirudin-based fibrinogen recognition peptide inhibitor, which binds efficiently to thrombin (IC50= 4.2 uM, in bovine),an enzyme involved in blood clotting. Hirullin peptide works by binding to thrombin and blocking its activity, thereby preventing the formation of blood clots.
  • Storage Guidelines
    Normally, this peptide will be delivered in lyophilized form and should be stored in a freezer at or below -20 °C. For more details, please refer to the manual: Handling and Storage of Synthetic Peptides

  • 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.
