Used in biomedical research to quantify levels of pyruvate dehydrogenase E1 (PDHE1) in human samples such as serum, plasma, or cell lysates. This ELISA kit enables researchers to assess PDHE1 protein expression in metabolic studies, particularly those related to glucose metabolism and mitochondrial function. It is widely applied in investigating diseases involving metabolic dysregulation, including diabetes, cancer, and neurodegenerative disorders. The assay provides a sensitive and specific means to monitor changes in PDHE1 under experimental conditions, supporting both clinical research and drug development efforts focused on cellular energy metabolism.
