Used in neuroscience and Alzheimer’s disease research to quantify levels of soluble amyloid precursor protein alpha (sAPPα) in biological samples such as cerebrospinal fluid, cell culture supernatants, and brain extracts. The kit enables researchers to study the non-amyloidogenic pathway of APP processing, which is considered neuroprotective. It is commonly applied in preclinical studies to evaluate the effects of drugs, genetic modifications, or cellular conditions on α-secretase activity. The assay supports high-throughput screening and provides a reliable tool for monitoring changes in sAPPα concentration associated with cognitive function, synaptic plasticity, and neurodegeneration.
