Used in neuroscience research to quantify levels of beta-secretase (BACE) activity associated with the processing of amyloid precursor protein in mouse models. This ELISA kit enables researchers to measure soluble BACE fragments or related amyloid-beta products in brain tissue homogenates, cerebrospinal fluid, or cell culture samples. It is particularly valuable in studies of Alzheimer's disease pathogenesis, where dysregulated BACE activity contributes to amyloid plaque formation. The kit supports high-throughput screening of potential therapeutic compounds aimed at modulating BACE expression or function in preclinical models.
