Used in biomedical research to quantify levels of pyruvate dehydrogenase kinase isozyme 3 (PDK3) in rat samples. This ELISA kit enables researchers to study PDK3 expression in metabolic studies, particularly in tissues involved in glucose metabolism such as liver, muscle, and heart. It is valuable in diabetes, cancer, and mitochondrial disease research where PDK3 plays a role in regulating the pyruvate dehydrogenase complex. The assay provides a sensitive and specific method to measure PDK3 protein concentration in cell lysates and tissue homogenates, supporting investigation into metabolic regulation and therapeutic interventions.
