Used in clinical and research laboratories to detect and quantify levels of Golgi protein 73 (GP73) in human serum or plasma samples. This assay is primarily applied in liver disease studies, especially for the early detection and monitoring of hepatocellular carcinoma (HCC). Elevated GP73 levels are associated with liver damage and malignancies, making this kit a valuable tool in biomarker research and diagnostic development. It supports immunoassay-based analysis with high sensitivity and specificity, enabling researchers to assess disease progression, evaluate treatment response, and explore GP73 as a potential diagnostic marker in liver-related conditions.
