Anti-Tau-1 Antibody, clone PC1C6

牛;人类;大鼠

Tau, a microtubulebinding protein which serves to stabilize microtubules in growing axons, is found to be hyperphosphorylated in paired helical filaments (PHF), the major fibrous component of neurofibrillary lesions associated with Alzheimer’s disease. Hyperphosphorylation of Tau is thought to be the critical event leading to the assembly of PHF. Six Tau protein isoforms have been identified, all of which are phosphorylated by glycogen synthase kinase 3 (GSK 3). Cellular and subcellular localization: In situ, anti-tau-1 has a stringent specificity for the axons of neurons. The antibody does not stain the cell bodies or dendrites of neurons, nor does it stain any other cell type (4). However, this in vivo intracellular specificity is not maintained in culture: anti-tau-1 stains the axon, cell bodies, and dendrites of rat hippocampal neurons grown in culture (5). The specificity of anti-tau-1 was originally thought to represent the restricted expression of tau to axons. Later studies revealed that this specificity is dependant on the state of phosphorylation. In dephosphorylated samples (samples treated with alkaline phosphatase) anti-tau-1 stains astrocytes, perineuronal glial cells, and the axons, cell bodies and dendrites of neurons, while in untreated samples, anti-tau-1 stains only axons (6). (The epitope recognized by anti-tau-1 is probably at or near a phosphorylated site.)

Binds to all known electrophoretic species of tau in human, rat and bovine brain (one-dimensional SDS-PAGE). However there is some unphosphorylated bias with clone PC1C6 as it seem to recognize only dephosphorylated serine sites at 195, 198, 199, and 202 {Szendrei, et al 1993; http://www.ncbi.nlm.nih.gov/entrez/query.fcgi-cmd=Retrieve&db=pubmed&dopt=Abstract&list_uids=7680727}. Also see Billingsley & Kincaid, 1997 Biochem J 323:577-591 for additional mapping information on PC1C6.
