Fetuin A ELISA kits are assays designed to detect the 64 kDa protein alpha-2-HS-glycoprotein (AHSG), also known as Fetuin A. Expressed and released by the liver, it plays a role in many physiological processes, such as bone metabolism, control of protease activity, and endocytosis. It is considered a biomarker for certain neurodegenerative diseases as the protein is commonly present in the cerebral cortex. Increased levels of fetuin A are associated with obesity and insulin resistance. Visit the supplier page for more information about detection range and reactivity.
