Phospho-Tau (T231) in Human Alzheimer's Brain. Tau phosphorylated at T231 was detected in immersion fixed paraffin-embedded sections of human Alzheimer's brain using Mouse Anti-Phospho-Tau (T231) Monoclonal Antibody (Catalog # MAB34941) at 5 µg/mL for 1 hour at room temperature followed by incubation with the Anti-Mouse IgG VisUCyte™ HRP Polymer Antibody (Catalog # VC001). Tissue was stained using DAB (brown) and counterstained with hematoxylin (blue). Specific staining was localized to cytoplasm in neurons.

Background: Tau

Tau is a microtubule-associated protein primarily expressed in neurons. It can associate with microtubules through the carboxy-terminal domains and with the plasma membrane through the amino-terminal projection domain. Tau has a role as a stabilizer of microtubules. Abnormal Tau phosphorylation or splicing is associated with various neurological disorders.
