Used to measure the activity of human isocitrate dehydrogenase (IDH) in biological samples such as cell lysates, serum, or tissue extracts. This ELISA kit enables researchers to quantify ICD levels in metabolic and cancer-related studies, especially in investigations involving cellular metabolism, mitochondrial function, and oncogenic mutations in IDH1 and IDH2. It is widely applied in clinical research to assess biomarker potential in gliomas, acute myeloid leukemia, and other cancers where IDH mutations play a key role. The assay supports high-throughput analysis and provides a reliable method for monitoring changes in enzyme activity during drug development and therapeutic evaluation.
