Used in neuroscience research to quantify phosphorylated tau (P-TAU) protein levels in mouse models, particularly in studies related to Alzheimer's disease and other tauopathies. Enables researchers to assess tau protein hyperphosphorylation, a key marker of neurofibrillary tangle formation, in brain tissue or cerebrospinal fluid samples. Supports evaluation of therapeutic interventions targeting tau pathology, including drug development and validation of genetic models. Provides a reliable, high-throughput method for detecting changes in P-TAU levels during disease progression or treatment.
