    Description

    Kinase, Natto fermentation is a potent fibrinolytic enzyme. Kinase, Natto fermentation can break down blood clots by directly hydrolyzing fibrin and plasmin substrate. Kinase, Natto fermentation can be used for the research of cardiovascular diseases[1].

    In Vitro

    Kinase, Natto fermentation dissolves 94% blood clot at ten minutes and degrades the fibrin clot after two hours of incubation[2].
    Product Information
    Molecular weight: 27728 Da (a single-chain polypeptide enzyme composed of 275 amino acids in a fixed arrangement) Acidity and alkalinity: relatively stable in neutral or alkaline environment (pH 7.0 ~12.0), extremely unstable when pH <5.0. However, the stability of nattokinase is greatly improved after mixing with boiled rice extract, broth, serum protein and gastric juice protein, and the enzyme activity will not be completely lost even under acidic conditions.
    Temperature: sensitive to high temperature, with better stability below 37°C, and it will be quickly inactivated due to protein denaturation when the temperature is higher than 60°C. Freeze-thaw: After repeated freeze-thaw cycles for 5 times, 95% of the original activity can still be retained.

    Instructions

    Help & FAQs
    • Do most proteins show cross-species activity?

      Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
