Recognizes a misfolded conformation of tau.


Raised against human basal forebrain homogenate. Epitope subsequently determined to include amino acids 2-10 and 312-342 of tau.


Recognizes a misfolded conformation of tau. 68 kDa Tau. Stains neuronal components of AD brain specimens but not normal brain specimens.

Comments / Questions

  1. This antibody recognizes a folded conformation of tau containing amino acids 2-10 and 312-342. We have used it successfully to detect misfolded tau in mouse models of tauopathy using array tomography, a relatively new imaging technique (Kopeikina et al., 2013).
