The Pyruvate Kinase (PK) Activity Assay Kit is widely used in biochemical research to measure the activity of pyruvate kinase, an enzyme crucial in glycolysis. It is commonly applied in studies focused on cellular metabolism, particularly in understanding energy production and regulation in cells. This kit is valuable in cancer research, as PK activity is often dysregulated in tumor cells, making it a potential biomarker for cancer progression. Additionally, it is utilized in drug discovery to screen compounds that modulate PK activity, aiding in the development of therapeutic agents. The kit is also employed in clinical diagnostics to assess metabolic disorders and enzyme deficiencies. Its simplicity and accuracy make it a preferred tool for researchers studying metabolic pathways and their implications in health and disease.
