Used to measure the activity of human β-glucosidase enzyme in biological samples such as blood, plasma, or cell lysates. This assay is commonly applied in clinical research and diagnostics to assess enzyme function in lysosomal storage disorders, particularly Gaucher disease, where β-glucosidase activity is deficient. The kit enables quantitative detection, supporting studies on disease progression, treatment efficacy, and enzyme replacement therapy monitoring. It is also used in drug development to evaluate compounds that modulate enzyme activity. High sensitivity and specificity allow reliable results in research settings focused on metabolic and genetic disorders.
