Used in neuroscience research to quantify tau protein levels in biological samples such as cerebrospinal fluid, brain tissue homogenates, or cell culture supernatants. Widely applied in studies related to neurodegenerative diseases, especially Alzheimer's disease and other tauopathies, where abnormal accumulation of tau is a key biomarker. Enables researchers to monitor disease progression, evaluate therapeutic interventions, and assess the effectiveness of drugs targeting tau aggregation or phosphorylation. The kit provides a sensitive and specific method for detecting both normal and pathological forms of tau, supporting biomarker validation and preclinical studies.
