Used in neuroscience research to quantify levels of tau protein in biological samples such as cerebrospinal fluid, blood, or tissue extracts. Helps in studying neurodegenerative diseases, particularly Alzheimer's disease and other tauopathies, where abnormal accumulation of tau is a hallmark. Enables researchers to assess disease progression, evaluate therapeutic interventions, and investigate mechanisms of tau pathology. The kit provides a sensitive and specific method for detecting both normal and phosphorylated forms of tau, supporting biomarker development and diagnostic research.
