The Solid-Sucrase (S-SC) Activity Assay Kit is used to measure the activity of sucrase enzyme immobilized on solid supports, such as beads or membranes. The primary applications are in research and development in enzyme technology, particularly in studying the efficiency and stability of immobilized enzymes, which is an important process in the food, chemical, and biopharmaceutical industries, such as the production of invert sugar from sucrose or improving fermentation processes. Additionally, it is used in analysis to check enzyme activity in various samples, which helps in quality control and developing more efficient products.
