The Glutamic-Pyruvic Transaminase (GPT) Activity Assay Kit is primarily used to measure GPT activity in biological samples, which is crucial for assessing liver function. Elevated GPT levels are often indicative of liver damage or diseases such as hepatitis, cirrhosis, or drug-induced liver injury. This kit is widely employed in clinical diagnostics to monitor liver health and evaluate the efficacy of treatments targeting liver conditions. Additionally, it is utilized in research settings to study liver metabolism, toxicity, and the impact of various compounds on liver enzymes. The assay provides a reliable and sensitive method for quantifying GPT activity, making it an essential tool in both medical and scientific investigations.
