Used in biomedical research to quantify gamma glutamyl transferase (GGT) levels in human serum, plasma, or other biological samples. Enables assessment of liver function, detection of hepatobiliary diseases such as hepatitis and cirrhosis, and monitoring of alcohol abuse. Widely applied in clinical laboratories and research settings for enzyme activity analysis without the need for radioactive materials. Supports studies on oxidative stress and drug metabolism due to GGT’s role in glutathione metabolism. Provides high sensitivity and specificity for accurate protein detection in immunoassay workflows.
