The Creatine Kinase (CK) Activity Assay Kit is widely used in clinical diagnostics to measure CK enzyme activity in blood samples, which is crucial for detecting and monitoring muscle damage, heart attacks, and other conditions affecting muscle tissue. In research, it helps study muscle metabolism and energy production, particularly in skeletal and cardiac muscles. The kit is also employed in pharmaceutical development to evaluate the efficacy and safety of drugs targeting muscle-related disorders. Its high sensitivity and accuracy make it a valuable tool for both diagnostic and experimental purposes.
