Used in biomedical research to quantify levels of acetaldehyde dehydrogenase 2 (ALDH2) in human biological samples such as serum, plasma, or tissue homogenates. This ELISA kit enables researchers to study ALDH2 expression in relation to alcohol metabolism, mitochondrial function, and oxidative stress. It is widely applied in studies investigating cardiovascular diseases, neurodegenerative disorders, and cancer, where ALDH2 activity is linked to cellular detoxification and protection against reactive aldehydes. The assay supports high-throughput screening and precise measurement, making it valuable in both clinical research and drug development.
