Y011106 is a rabbit polyclonal antibody specific for Tau (MAPT) phosphorylated at Serine 235, a proline-directed phosphorylation site associated with neurofibrillary pathology in Alzheimer's disease and other tauopathies. Validated for Western blot (WB) at 1:500–1:2,000, it detects pSer235-Tau at 50–80 kDa and does not recognize non-phosphorylated Tau.
