The γ-Glutamyltranspeptidase (γ-GT) Activity Assay Kit is primarily used in clinical diagnostics to measure the activity of the γ-GT enzyme in biological samples. This enzyme is a key biomarker for liver and biliary tract diseases, making the kit essential for assessing liver function and detecting conditions such as hepatitis, cirrhosis, and cholestasis. It is also employed in toxicology studies to evaluate the impact of drugs or toxins on liver health. In research, the kit is utilized to study the role of γ-GT in cellular processes, including glutathione metabolism and oxidative stress. Its high sensitivity and specificity make it a valuable tool for both diagnostic and experimental purposes.
