Enzyme assays are laboratory tests used to measure the activity of enzymes, which are proteins that speed up chemical reactions in living organisms. These assays help scientists understand how enzymes function, their efficiency, and how they can be affected by various factors such as temperature, pH, and the presence of inhibitors or activators. There are different types of enzyme assays, including colorimetric assays, fluorometric assays, and kinetic assays. Each method has its own advantages and is chosen based on the specific enzyme being studied and the desired information. Enzyme assays are essential in fields like biochemistry, pharmacology, and clinical diagnostics.
