| Tau is a heterogeneous group of proteins that range in molecular weight from 50-67kD. They are instumental in the assembly of microtubules and have been associated with some disease states. In normal brain, tau is localized in the axons of the neurons but in some neuropathological lesions, it accumulates within the body of the neuron. Tau protein is a microtubule-associated protein predominantly localized to neuronal axons. Tau promotes tubulin polymerization and the stabilization of microtubules. Hyperphosphorylated forms of Tau are the major components of paired helical filaments (PHF) found in the neurofibrillary tangles which characterize Alzheimer’s disease. Alternate splicing of tau mRNA, glycosylation, and differential phosphorylation contribute to the heterogeneity of tau. |

| Catalog # | T1030-40B1 |
| Applications | Suitable for use in Western Blot, Immunohistochemistry and Differential Detection of Tauopathies. Other applications not tested. |
| Recommended Dilutions | Western Blot: 1:1000-1:4000 detects Tau (3-repeat isoform RD3) in lysates from rat brain cytosol fraction. Rat brain cytosol fraction was resolved by electrophoresis, transferred to nitrocellulose and probed with T1030-40B1. Proteins were visualized using a IgG (HRP) Gt x Mo and a chemiluminescence detection system. |
| Immunohistochemistry: Detects Tau (3-repeat isoform RD3) in autoclaved paraffin brain sections (1). |
| Differential Detection of Tauopathies: See Ref. 2. |
| Optimal dilutions to be determined by the researcher. |
| Recommended secondary antibodies | I1904-06C: IgG, H&L (HRP) (X-Adsorbed) Pab Gt xMo |
| I1904-06H: IgG, H&L (HRP) (X-Adsorbed) Pab Gt xMo |
