Used in biomedical research to measure acetaldehyde dehydrogenase (ALDH) enzyme levels in biological samples such as blood, tissue lysates, and cell cultures. This kit enables researchers to quantify ALDH activity indirectly by detecting protein concentration, supporting studies on alcohol metabolism, liver function, and oxidative stress. It is widely applied in toxicology, addiction research, and disease biomarker discovery, particularly in conditions linked to mitochondrial dysfunction and metabolic disorders. The assay is also useful in cancer research, as elevated ALDH levels are associated with cancer stem cells in tumors such as breast, lung, and ovarian cancers. Its high sensitivity and specificity make it suitable for preclinical studies and drug development where monitoring ALDH expression is critical.
