Phosphoenolpyruvate Carboxykinase (PEPCK) Activity Assay Kit is widely used in research to measure the activity of PEPCK, an enzyme crucial in gluconeogenesis. It helps in studying metabolic pathways, particularly how the liver and kidneys convert non-carbohydrate sources into glucose. This kit is essential in diabetes research, as it provides insights into glucose regulation and insulin resistance. Additionally, it is used in cancer studies to understand tumor metabolism, where altered gluconeogenesis is often observed. The kit is also valuable in nutritional and physiological studies, helping to explore the effects of diet, fasting, and exercise on metabolic processes. Its applications extend to drug development, where it aids in evaluating compounds targeting metabolic disorders.
