Used in biomedical research to quantify levels of human isocitrate dehydrogenase in biological samples such as serum, plasma, or cell lysates. This ELISA kit enables detection of ICD activity associated with cellular metabolism studies, particularly in cancer research where mutations in IDH enzymes are linked to gliomas and acute myeloid leukemia. It supports investigation into metabolic pathways, mitochondrial function, and epigenetic regulation by providing a reliable method to measure enzyme concentration. Widely applied in clinical labs and pharmaceutical development for biomarker validation and monitoring therapeutic responses.
