Used for the quantitative measurement of α-Mannosidase (αManase) activity in rat biological samples such as serum, plasma, tissue homogenates, and cell culture supernatants. This ELISA kit enables researchers to assess lysosomal enzyme activity associated with glycoprotein metabolism, supporting studies on lysosomal storage disorders, neurodegenerative diseases, and immune system function in rat models. The assay is useful in preclinical research for monitoring disease progression or evaluating therapeutic interventions targeting enzyme replacement or metabolic pathways. High sensitivity and specificity allow for accurate detection of αManase levels, even in small sample volumes.
