The Pyruvate Kinase (PK) Activity Assay Kit is widely used in biochemical research to measure the enzymatic activity of pyruvate kinase, a key enzyme in glycolysis. It is essential for studying cellular energy metabolism, particularly in cancer research, as PK activity is often dysregulated in tumor cells. The kit is also employed in drug discovery to screen potential inhibitors or activators of PK, aiding in the development of therapeutic agents. Additionally, it is utilized in clinical diagnostics to assess metabolic disorders and monitor enzyme activity in blood samples, providing insights into conditions like hemolytic anemia or other metabolic diseases. Its applications extend to agricultural research, where it helps analyze metabolic pathways in plants under stress conditions. The kit offers a reliable and sensitive method for quantifying PK activity in various biological samples.
