Used in neuroscience and Alzheimer’s disease research to quantify soluble amyloid precursor protein alpha (sAPPα) in biological samples such as cerebrospinal fluid, cell culture supernatants, and brain extracts. The kit enables researchers to monitor sAPPα levels as a biomarker for non-amyloidogenic processing of APP, reflecting neuronal health and synaptic activity. It supports studies on neuroprotection, cognitive function, and drug development targeting amyloid-beta reduction. The assay is suitable for high-throughput screening and provides a reliable tool for investigating the balance between neuroprotective (sAPPα) and neurotoxic (amyloid-beta) pathways in neurodegenerative conditions.
