Used in biomedical research to quantify levels of human pyruvate dehydrogenase E2 (PDHE2) in biological samples such as serum, plasma, or cell lysates. This ELISA kit is particularly valuable in studies related to mitochondrial function, metabolic disorders, and autoimmune diseases like primary biliary cholangitis (PBC), where PDHE2 acts as a major autoantigen. The assay enables researchers to detect and measure specific immune responses or protein expression changes associated with metabolic dysregulation. Its high sensitivity and specificity make it suitable for both clinical research and drug development settings where accurate measurement of PDHE2 is required.
