Phosphoenolpyruvate Carboxykinase (PEPCK) Activity Assay Kit is widely used in metabolic research to study gluconeogenesis, the process by which organisms generate glucose from non-carbohydrate sources. It is particularly valuable in understanding liver and kidney function, as these organs are primary sites of gluconeogenesis. Researchers utilize this kit to measure PEPCK enzyme activity, which is crucial for assessing metabolic disorders such as diabetes, obesity, and insulin resistance. Additionally, it aids in investigating the effects of drugs, hormones, and nutritional changes on glucose metabolism. The kit is also employed in agricultural and environmental studies to analyze metabolic pathways in plants and microorganisms, providing insights into energy production and carbon fixation processes. Its applications extend to biotechnology, where it supports the development of bioengineered organisms for improved metabolic efficiency.
