Used in biomedical research to detect and quantify lysosomal enzymes or proteins associated with lysosomal function in cell or tissue samples. Commonly applied in studies of lysosomal storage disorders such as Gaucher disease, Niemann-Pick disease, and Tay-Sachs disease to assess enzyme activity or biomarker levels. Enables researchers to monitor disease progression, evaluate therapeutic efficacy in drug development, and study cellular autophagy mechanisms. Widely used in academic labs, pharmaceutical research, and clinical diagnostics for high-throughput screening and biomarker validation.
