Used in immunological research to quantitatively measure mouse β-hexosaminidase (β-Hex) levels in biological samples such as cell lysates, tissue homogenates, and serum. This assay is commonly applied in studies related to lysosomal storage diseases, particularly Tay-Sachs and Sandhoff diseases, where β-Hex enzyme activity is impaired. The kit enables researchers to assess enzyme expression and secretion in immune cells like macrophages and microglia, making it valuable in neuroinflammation and neurodegenerative disease research. It is also used in drug development to evaluate therapeutic efficacy of enzyme replacement or gene therapies targeting lysosomal function in mouse models.
