Used in biomedical research to quantify levels of human α-mannosidase enzyme in biological samples such as serum, plasma, or cell lysates. This ELISA kit is particularly valuable in studying lysosomal storage disorders, especially alpha-mannosidosis, where enzyme activity is deficient. It enables researchers to monitor enzyme replacement therapies, assess disease progression, and evaluate the efficacy of new treatments. The assay is also applied in immunology and cancer research due to the enzyme's involvement in glycoprotein processing and immune cell function. Its high sensitivity and specificity make it suitable for clinical diagnostics and laboratory investigations requiring precise measurement of α-mannosidase protein concentrations.
