Tau Antibody (1032501) [Unconjugated]

Tau was detected in immersion fixed paraffin-embedded sections of human brain (Alzheimer's) using Mouse Anti-Human Tau Monoclonal Antibody (Catalog # MAB106291) at 5 µg/mL for 1 hour at room temperature followed by incubation with the Anti-Mouse IgG VisUCyte™ HRP Polymer Antibody (VC001). Before incubation with the primary antibody, tissue was subjected to heat-induced epitope retrieval using Antigen Retrieval Reagent-Basic (CTS013). Tissue was stained using DAB (brown) and counterstained with hematoxylin (blue). Specific staining was localized to cytoplasm in neurons and neuronal processes. Staining was performed using our protocol for IHC Staining with VisUCyte HRP Polymer Detection Reagents.

Background

Tau protein is named for its ability to serve as a bridge for microtubule formation and stabilization. Tau in PNS neurons is 758 amino acids (aa) in length and 110 kDa in size. It migrates anomalously in SDS-PAGE. Its N-terminus binds plasma membrane components while its C‑terminus binds microtubules. The microtubule-binding region contains four consecutive Tau/MAP repeats between aa 561‑685. Each repeat is 30 aa long, Ser/Thr rich, and shows a PGGG motif. Multiple isoforms exist, ranging from 316 to 776 aa in length. Various deletions occur within the first 500 aa, with some isoforms also showing an absence of the second Tau repeat (aa 592‑622). Between aa 624‑756, human Tau protein shows absolute identity to mouse and dog Tau.
