Used in biomedical research to quantify levels of human fumarase (FUM) in biological samples such as serum, plasma, or cell lysates. This ELISA kit enables detection and measurement of fumarase, an enzyme involved in the tricarboxylic acid (TCA) cycle, supporting studies related to mitochondrial function, cellular metabolism, and oxidative stress. It is particularly useful in research on metabolic disorders, neurodegenerative diseases, and cancer, where dysregulation of metabolic enzymes may occur. The assay provides a sensitive and specific means to monitor fumarase expression and assess its role in disease mechanisms or therapeutic responses.
