Used to measure β-mannosidase enzyme activity in biological samples from mice. This kit is commonly applied in research on lysosomal storage disorders, particularly to study enzyme deficiencies related to glycosphingolipid metabolism. It enables quantification of β-mannosidase levels in tissue homogenates, cell lysates, or serum, supporting investigations into disease mechanisms, gene therapy efficacy, and enzyme replacement treatments in mouse models. The assay is useful in preclinical studies for metabolic and neurodegenerative diseases.
