    A new assay uses milk coagulation to quantify proteases, offering a sensitive method for enzyme detection. This technique precisely measures enzyme activity by monitoring milk clotting times.

    Area of Science:

    • Biochemistry
    • Enzymology
    • Food Science

    Background:

    • Proteases are enzymes that break down proteins.
    • Milk coagulation is a complex process influenced by enzymatic activity.
    • Existing methods for protease detection can lack sensitivity or precision.

    Purpose of the Study:

    • To develop a quantitative and sensitive assay for proteases.
    • To adapt milk coagulation as a measurable indicator of protease activity.
    • To establish a precise method for enzyme activity determination.

    Main Methods:

    • Utilizing a clot timer to monitor milk coagulation.
    • Employing buffered milk as a substrate for protease interaction.
    • Quantifying protease activity based on clotting time.

    Main Results:

    • The milk coagulation assay demonstrated sensitivity to protease activity.
    • The clot timer provided precise measurements of the coagulation phase.
    • The assay successfully adapted enzymatic milk coagulation into a quantitative method.

    Conclusions:

    • Milk coagulation can be adapted into a sensitive and quantitative protease assay.
    • The developed assay offers a precise method for detecting and measuring protease activity.
    • This technique has potential applications in various fields requiring enzyme analysis.
