    Researchers developed a novel method to stabilize human thrombin using organic ligands like rosselin and orange II. This approach enhances enzyme stability and catalytic activity, offering a promising alternative to traditional additives.

    Area of Science:

    • Biochemistry
    • Enzyme Stabilization

    Context:

    • Enzyme stability is crucial for practical biocatalysis.
    • Environmental factors and macromedium composition significantly impact enzyme stability.
    • Traditional additives like salts and polyols are commonly used for enzyme stabilization.

    Purpose:

    • To introduce a new method for stabilizing human thrombin using organic ligands.
    • To investigate the efficacy of organic ligands (rosselin, orange II) as stabilizing agents for thrombin.
    • To compare the stability of thrombin under various conditions and concentrations.

    Summary:

    • A novel method for human thrombin stabilization using organic ligands with ionic and hydrophobic groups was developed.
    • Rosselin and orange II were identified as highly effective ligands, with optimal concentrations around 0.0012-0.0014 M.
