Tau is a microtubule-associated protein. In adult human brain, 6 tau isoforms are expressed, which are divided into two
groups, 3-repeat (3R) and 4-repeat (4R) tau isoforms. Tau assembles into insoluble, filamentous, and
hyperphosphorylated inclusions in many neurodegenerative diseases, and different tau isoforms are accumulated in the
diseased brains, namely, 6 tau isoforms in AD, 3R tau isoforms in Pickfs disease, and 4R tau isoforms in PSP and CBD.
Therfore, isoform-specific tau antibodies are useful tools for immunohistochemical and biochemical studies of tau
species in diseased brains. Tau deposited in AD is extensively deamidated at N279. This anti-4R specifically recognizes
4R tau isoforms regardless of deamidation and strongly stained tau in AD brain.
