Used in neuroscience and Alzheimer's disease research to detect and quantify phosphorylated tau protein levels in biological samples such as cerebrospinal fluid or brain tissue extracts. The kit enables researchers to study tau pathology, which is a key hallmark of neurodegenerative diseases including Alzheimer's. It supports investigation into disease progression, evaluation of therapeutic interventions, and biomarker development for early diagnosis. Widely applied in preclinical studies and drug development to assess the effectiveness of compounds targeting tau hyperphosphorylation.
